Manual drill and why the tool is used

Few people know what can be done from the old drill, so do not rush to dispose or sell this invaluable tool. From it you can make a screwdriver for screwdriver, which is designed to screw and unscrew different fasteners. It can be not only long screws, but also bolts with nuts. The secret of this device is that you can make a very useful thing from the old drill, which will allow you to get to hard.To.Reach places with the subsequent unscrewing of fasteners.

The principle of manufacturing nozzle or device for a screwdriver from a hand drill is to perform such manipulations:

  • First, we release the tool from unnecessary details. To do this, dismantle the cartridge from the tool, as well as the handle
  • A stubborn heel is also dismantled, which will not be needed in the new device
  • The shaft on which the cartridge was located has a fairly large diameter. It will not work to install a shaft of such a diameter in the cartridge of the screwdriver, so we proceed to its grinding
  • Ground shaft to reduce its diameter is recommended on a lathe. The use of an emery circle or grinder for such purposes is not recommended, since the grinding will turn out to be uneven
  • To hide the shaft on a lathe, it will need to initially dismantle it from the tool. It is not difficult to do it. In the mechanism near the conical gear, which is planted on the shaft, there is a hole with a cobble. This Shplint must be knocked out, thereby separating the gear from the shaft
  • After gathering the shaft up to 8-10 mm on a lathe, it should be installed in place, not forgetting to sprinkle. The shaft is made of hot steel, so before you grind it, it is recommended to carry out heat treatment (heat it with a soldering lamp)
  • The shaft moves using a ball bearing, which can be lubricated to extend its service life
  • The first part of the work was completed. The shaft, which was stood, will be used on the new device as a transmitted device. The working element on the device will be a shaft on which the handle was attached
  • The second shaft has a specific hexagonal shape, which should also be processed so that it can be put on it end heads or other nozzles. The easiest option is to make a square entity from the hexagonal form of the end protrusion of the head
  • You can do this with a grinder and a cutting circle. At the same time, only heads can be installed on such a shaft for screwing and unscrewing bolted joints
  • If you plan to use a device for other purposes, then you can cut threads on the shaft, having previously made it a cylindrical shape and turning it to the desired size
  • On the chopped thread, it is necessary to screw the cartridge from the drill, in which various nozzles can be installed. Bats, mixers, drills, cutters, etc.P.
  • Consider that to install the cartridge on the secondary shaft of the device, you will also need to cut the internal thread for the control fixing of the cane cartridge
  • At the end of the manufacture of the device from the old manual drill, it is necessary to cut off the rest on which a stubborn paw was attached
  • After that, a home.Made device is ready for use. It remains to fix it in the cartridge of the screwdriver, and test

The advantage of such a device is to increase the strength of the moment. The screwdriver sets in motion the gear of small diameter, which transfers the force to the larger six. A small, transmitted force to the second large gear, on which the secondary shaft is located, is attached to the large gear, thereby reduced rotation speed, which means that the moment intensifies. As a result, the device allows you to unscrew and tear off the bitten and rusted bolted joints. However, do not forget that the main role is played by a screwdriver that should have the necessary power supply, otherwise its engine may suffer.

What is the difference between a manual drill and a collar?

If a Kolovorot It is a crankshaft with a coat-heal and a cartridge for fixing the cutting part, then Hand drill It consists of a gear gear planted on a transfer shaft with a cartridge at the end, a handle for rotating a gear, shoulder stop and handle for additional support for the tool.

Two.Speed manual drills somewhat more complex in design, device based on a mechanism called a two.Stage multiplier. This is a mechanical gearbox consisting of a set of gears combined on several axes in one building.

Advantages and disadvantages

Each tool has its own advantages and disadvantages. The product in question has the following disadvantages:

  • The physical strength necessary to perform drilling work. Currently, it will not hurt to sometimes work with muscles
  • Length of the product. When working, such a tool is convenient, which can not be said about its transportation
  • Large weight, which sometimes exceeds the mass of electrical analogues
  • Lack of the need to connect the tool to an electric network. The device works depending on the presence of physical strength for the user
  • Low cost, even today manual modifications of drills are produced, the cost of which does not exceed 1000 rubles. However, the quality of these products is inferior to those that were released during the USSR
  • Simple design. The simplicity of the design affects the cost of the unit, which is so low, as well as reliability. The simpler the design of the tool, the more reliable it is, and it can independently repair it

How to work with a mechanical drill

Safety rules are respected when working with any tools, including manual. They are no less dangerous than electric if they are not right to use. To avoid serious injuries, you need to follow the following recommendations:

  • Secure reliably the detail that is planned to process
  • When drilling, the drill heats up, so periodically you need to pause so that the nozzle cools down
  • It is recommended to use the product in protective glasses

Now it is known what a manual mechanical drill is, for which it is needed, and how to use it correctly. If you are going to dispose of the tool, then you should think carefully again. Even if this material did not convince to leave the tool in its set, then it can be sold for an acceptable price of up to 600 rubles, depending on the model. You can buy new products in online stores or special tools for the sale of tools. Below is a video file, after watching which, you definitely will not want to get rid of the product.

Despite the stably growing popularity of an electrified tool, the use of manual drills continues to be very relevant. Their choice is relatively small, however, all of them can boast of many obvious advantages with a minimum amount of minuses. The validity of this thesis is confirmed by both domestic and foreign craftsmen who continue to use these tools to successfully solve various household problems.

Varieties

Depending on the features of their design, the described tools are one- and two-speed tools. The former are used relatively rarely, which is explained by their low efficiency, while the latter are used much more often, since they have a more advanced design and are able to solve a variety of problems.

Single.Speed

The classic manual drill related to this variety suggests the presence of a pair of gears, the rotation of which drives the cartridge in motion. Most often, such tools are open. Not providing for the use of a protective case.

As for the location of the gears, the large of them is associated with the handle, and the smaller one. With the cartridge. Another feature of such drills is the presence of a handle, thanks to which you can reliably fix the tool during operation.

Two.Speed

The type of manual drill under consideration involves the presence of a multiplier. A mechanical device, which is also called an accelerator.

In order to change the speed of such a drill, it is enough to set the handle on the other side. This action leads to an increase or decrease in the gear ratio, which naturally affects the performance of the tool used. There are also such drift models in which a longitudinal displacement of the axis of rotation of the handle is provided to change the speed, and not the above.Mentioned rearrangement.

Also mechanical drills differ depending on the type of cartridge used. Its design may include the presence of three or four fists. Clamping elements that provide reliable fixation of a rotating tool.

Battery model

Wireless drills are very popular among home masters, because the work is not limited to the length of the wire, which allows their use in any conditions. They also belong to an electrical tool. There are options when the charger is located in the case for storing the tool, and after operation it is stored and at the same time charges. Basically, the batteries have two spare blocks, which are enough for work.

Such a shy battery is charged for no more than an hour, so you will not take large breaks when you planned a large amount of work for the day. As a rule, the charging unit is designed several thousand times, but specifically you need to find out this indicator when buying, there are replaceable batteries more expensive, which charge in 15 minutes.

Varieties of structures

Experts divide the mechanical drills into two main types.

Developers from different countries fought over the problem for a long time: how to make sure that a simple hand drill could work at two speeds. For these purposes, it was invented Two.Stage multiplier. The original design of the gearbox, which has a set of gears in its asset, compiled on different axes in a single building.

To switch the drilling rate, it is necessary to rearrange the rotation handle to the other side. The gear ratio of the gearbox increases or decreases, accordingly, the number of revolutions of the cartridge for one scroll of the handle also changes.

The main difference between this model is a gearbox: it is closed and is located in a special case, but, as in the first version, it is easily disassembled, all parts are available for cleaning and lubrication.

The figure below shows a two.Handed version of a hand drill:

Safety and subtleties of choice

A manual drill is a simple tool that does not require special skills to work. However, as when working with other devices, it is necessary to observe simple rules that allow to minimize the likelihood of a breakdown of the working part or a person: a person:

  • The workpiece should be recorded. With any attempts to hold it with hands quite often situations when the part breaks out of the fingers, simultaneously injuring;
  • Do not touch the drill with your hand, not making sure that it has cooled (burns are not uncommon, especially if the metal is drilled);
  • After replacing the drill, do not forget the key in the cartridge;
  • When drilling at high speed, it is better to take breaks to excess the drill overheating. And the drill will be better, and the work will eventually be completed better;
  • Using glasses will protect the eyes from chips.

When choosing a hand drill, you should pay attention to the convenience of handles, smooth rotation of the mechanism, accuracy of execution. There should be no burrs, sharp protruding edges, other signs of poor.Quality production on the corps. The negligence of execution indicates, as a rule, of the low quality of production, which negatively affects products.

As practice shows, the mechanical drill is still in demand, despite the fact that today there is a huge selection of “electricians”. It is clear that the work with this tool is more tiring and slow compared to the drilling of an electric drill or a screwdriver, so in professional activities a hand drill is rarely used. However, to perform simple household tasks, this tool can be effective and practical, allowing you to do the same work without access to the mains, without hurrying, but keeping the process completely under control.

Hand drills and the relevance of the use of obsolete tools

The existence of instruments such as hand drills, many young masters are not even aware of. Having first seen this tool, the question arises, why is it needed if everything has been using electric. Hand tools have been very popular since the time of the Soviet Union. With the advent of an electric tool, manual devices were forgotten, but did not disappear at all. Surely each master of the age of 40 has in the arsenal the device in question, which can periodically benefit.

The first invention of a person, with which manually drill holes in concrete and tree was called a collar. On the basis of the columge, manual or mechanical types of drills (and after and electric) were invented, which gained wide popularity. The columnar has the form of a curved frame, which is equipped with a cartridge for fixing the drills.

The columnar was not a very convenient device when working, which was distinguished by developers to create a hand.Type drill. There is no need to return to the past, so let’s dwell on the question of where a device such as a manual drill is now being used now.

The use of such drones today is no longer as relevant as 30 years ago, but they are still used to screw screws and screws. For such purposes, screwdrivers are used, but not everyone has such tools. Sometimes the power of the screwdriver is simply not enough to screw the screws into a wooden or plastic base. The screwdriver is also problematic, so the manual apparatus always comes to the rescue.

The product is also used to drill holes with crowns. The screwdriver has a low power for working with crowns, and the drill has a high speed of rotation of the cartridge. Drilling large holes with a manual tool, although it will take more time, but at the same time will definitely not lead to a breakdown of the tool. The tool under consideration cannot be called the most necessary, but you should also not rush to get rid of it also. In addition to home workshops and garages, where the tools in question are used very rarely, they are also used in medicine. Without its help, it becomes simply impossible to conduct operations on bone tissues and when installing knitting needles for bones.

Electric counterparts, although they are able to perform work ten times faster, but they have not such a large power supply as hand products. It is problematic to drill a hole in the metal with a manual device, however, it will not be difficult to make a hole in wood or concrete.

Hand drill device

Mechanical drills, as a rule, are divided into single.Speed and two.Speed. The latter are considered more practical and universal, despite the fact that the design is slightly more complicated. However, it becomes possible to change the speed of rotation, which expands the scope of application.

Manual hand drill restoration

A manual mini-spar, having one rotation speed, technically represents a couple of gears, with which rotation from the handle to the cartridge is transmitted. Quite often, gears do not even hide in the case, but leave open.

On a large lead gear there is a handle, which is driven by a mechanism, a small (led) gear is recorded on a common shaft with a cartridge. On the opposite from the cartridge, the end of the device is mounted a stubborn handle that allows you to hold the tool and direct it. The design is simple, due to which the manual drill has phenomenal reliability and almost never fails.

manual, drill, home, crafts

Two.Speed hand drills are somewhat more complex in design, the device is based on a mechanism called a two.Stage multiplier. This is a mechanical gearbox consisting of a set of gears combined on several axes in one building.

In order to change the speed of rotation, the handle is reinstalled to the desired side, while the gear ratio of the gearbox and, accordingly, the number of revolutions of the cartridge in one turn of the handle changes. In fairness, it should be noted that there are models where the switching of the speeds occurs using the longitudinal displacement of the axis of the rotation of the handle and to change the frequency of rotation of the cartridge to twist the handle itself, there is no need.

In general, a manual drill is a device that has a shoulder stop, one handle for rotating the cartridge and a handle located on the other side to hold the tool.

The cartridge can be of different models, three- or four-cup. The rotated handle is fixed on the shaft, as a rule, by a contrastent screw. Stubborn screws into the case on the right or left. If necessary, all the details can be removed, the gear is cleaned and lubricated.

The electric drill is a popular construction and mounting tool that performs drilling work. On this area of ​​its use does not end. Due to the mass of nozzles, the tool can perform a whole set of functions, starting from stirring building mixtures, polishing and ending the sharpening of drills.

Device and principle of action

The drill is a compact and light design, the main parts of which are:

The principle of operation of the drill is that the electric engine transfers torque through the gearbox to the cartridge that fixes the drill. Thanks to the use of the reducing speed of the mechanism, the drill spins a little slower than the engine itself, but at the same time has increased strength, so it does not stop when resisting.

Varieties of drones

The drill is a fairly simple tool that has a simple design. Nevertheless, there are several of its varieties that differ in the structure of the gearbox and have various directions of use. Drills are the following types:

Each of these tools has its own advantages and disadvantages. All of them are suitable for drilling, but have various additional functions. When choosing a tool, you need to decide for what tasks it will be used, which will facilitate further operation.

The usual design

The usual drill is very compact and light. It can be used to drill wood, plastic and metal. It provides the creation of a neat hole. Such a tool often has the ability to adjust the revolutions, which is useful if it is necessary to drill specific materials, when it is undesirable to bring the drill to overheating. Almost all models of ordinary drills are equipped with a receiver. When switching it, the direction of rotation of the cartridge changes. This allows you to turn the drill if it gets stuck.

Shock structure

Shock drills have a slightly changed gearbox, in which two gears are added. As a result of the rotation of the engine, not only the transfer of revolutions to the cartridge is ensured, but also its sharp reciprocating movement. Due to this, drilling has a chisel effect. It is necessary when working with stone, concrete and brick. Shock models allow you to drill walls, while ordinary drills cannot.

In this case, shock drills have two operating modes. In the first, a simple rotation of the cartridge occurs, as in the usual design, and in the second additional gears are involved, which provide reciprocating movement. At first glance, the shock structure is similar to a perforator, but this is not so. The perforator uses a pneumatic mechanism, which is more reliable and effective, so that the holes break through are faster.

Mixer type

The mixer drill has a more enlarged gearbox. Thanks to this, it has significant force, but gives out low speeds. Such a tool is heavier than the first two varieties and works slower. Despite this, it is quite possible for them to drill metal, plastic and wood. The advantage of the mixer structure is the high dragging power of the gearbox. By installing a special nozzle with blades in the cartridge, it is possible to knead building mixtures such as concrete, glue or plaster.

Slarly type

A screwdriver drill can be used for drilling as ordinary, as well as screwing and twisting screws. It has a wide range of rotation speed adjustment. In addition, its design provides for a special rattles. Its task is to turn off the transmission of rotation to the cartridge with a certain effort, the strength of which is set using an adjusting scale. This is necessary to prevent torn threads in the landing hole of the screw.

The pros and cons of such a drill

Like the power tool, the manual drill also has its advantages and disadvantages. First you should list the advantages:

  • Simplicity of design. The simplest design of the tool allows you to reduce the cost of the tool, as well as increase the reliability. Modern manual units are made from not as high.Quality materials as in the USSR. But nevertheless, such a product is difficult to break, and even if any breakdown occurs, it is eliminated quite easily, quickly and independently.
  • Lack of need to connect to electricity. The tool can be operated in the field, which increases the functionality of the device.
  • Low cost. Today you can purchase a new mechanical drill for a maximum of 1000 rubles, but it is the outdated models that can be more popular, which can be purchased from 400 rubles.

As for the shortcomings, then the device in question also has. These include:

  • The need to apply physical strength. Sometimes this property is very useful, as it allows you to pump muscles.
  • Large dimensions of the product. Despite the simplicity of the design, the product has large sizes than power tools, which complicates its transportation.
  • Light weight of some models. The weight of the tool depends on the materials from which the details of the device are made. If cast iron is used, then the mass of the tool reaches 2-3 kg.

Hand drill device

Mechanical drills, as a rule, are divided into single.Speed and two.Speed. The latter are considered more practical and universal, despite the fact that the design is slightly more complicated. However, it becomes possible to change the speed of rotation, which expands the scope of application.

A manual mini-spar, having one rotation speed, technically represents a couple of gears, with which rotation from the handle to the cartridge is transmitted. Quite often, gears do not even hide in the case, but leave open.

In general, a manual drill is a device that has a shoulder stop, one handle for rotating the cartridge and a handle located on the other side to hold the tool.

The cartridge can be of different models, three- or four-cup. The rotated handle is fixed on the shaft, as a rule, by a contrastent screw. Stubborn screws into the case on the right or left. If necessary, all the details can be removed, the gear is cleaned and lubricated.

What is a shock drill for

Everyone who is just starting to take their first steps in comprehending the basics of repair, usually gain their experience with simple types of work, somehow: score a nail, screw a self-tapping screw, prepare a wallpaper glue, drill a hole in the wall, etc. P. Of course, many work can be done manually, dispensing without power tools. However, when making repairs, you need to remember the convenience and time spent. You can, for example, twist a couple of screws with your hands with a screwdriver and hang a shelf. Another thing is if you need to fix a sheet of a giper the size of a half room to the guides, where you need to fasten from half a hundred self.Tapping screws. Here, perhaps, you won’t wrap your hands. You will get tired quickly! And here, then you begin to think about how it would be more quickly and with less costs to make.

Here we can say, why are we talking about a shock drill? After all, for this you can use a regular drill with a nozzle to tighten screws, and even easier to take a screwdriver. Everything is right. But for beginners in the repair, buying several expensive power tools at once may be consistent. In this article I want to show how one tool can be turned into several and at first it is great to do it.

In the classic performance, the tool consists of the following main parts:

At the top on the drill housing, a fixed stubborn hilt is fixed. On the side of it on the mobile axis, a large drive gear associated with a mobile handle is fixed on the side of it. When the latter rotates, the gear turns.

A small slotting gear is applied to a large driven. The spindle is attached to it, at the end of which the cartridge is installed. The layout of the gears works like a gearbox. One turnover of a large presenter is accompanied by several small led. This is the reason for the higher performance of the hand drill in comparison with the collar.

Application area

Hand drills are also called a collar or mechanical drills. In the days of the USSR, such a device was an indispensable tool not only during repair work, but also for the household as a whole. Previously, such a drill was called a collar, as it was constructively curved frame with a cartridge to fix the drill.

The improvement of the collarge led to the fact that a hand drill was created, structurally consisting of a cartridge, handle, as well as a gearbox with gears. The use of such devices in the days of the USSR was carried out to carry out a number of various works. Today, power tools are used for such work, but still there are spheres where manual devices still continue to be popular.

A manual drill allows you to drill holes in wood, concrete, metal and other materials. The only drawback is the need to rotate the cartridge by hand by hand, through the gearbox. Today, such products have found their application in screwing screws. Electric screwdrivers can cope with this task quickly and easily, but very often there are such moments when the power of the power tool is simply not enough to screw the screws to the end. A hand drill comes to the rescue, whose screwing force directly depends on the physical state of a person.

As before, today, in medicine, a manual drill is the most necessary tool that is intended for drilling bones, which is done to install knitting needles in them. In addition, the mechanical tool has found its application for marking. Various tools, and a columnar, including. In addition, with the help of a mechanical tool, drilling existing holes, zenching and even a scan is carried out, so do not rush to throw away such a useful type of tool.

The pros and cons of such a drill

Like the power tool, the manual drill also has its advantages and disadvantages. First you should list the advantages:

  • Simplicity of design. The simplest design of the tool allows you to reduce the cost of the tool, as well as increase the reliability. Modern manual units are made from not as high.Quality materials as in the USSR. But nevertheless, such a product is difficult to break, and even if any breakdown occurs, it is eliminated quite easily, quickly and independently.
  • Lack of need to connect to electricity. The tool can be operated in the field, which increases the functionality of the device.
  • Low cost. Today you can purchase a new mechanical drill for a maximum of 1000 rubles, but it is the outdated models that can be more popular, which can be purchased from 400 rubles.

As for the shortcomings, then the device in question also has. These include:

  • The need to apply physical strength. Sometimes this property is very useful, as it allows you to pump muscles.
  • Large dimensions of the product. Despite the simplicity of the design, the product has large sizes than power tools, which complicates its transportation.
  • Light weight of some models. The weight of the tool depends on the materials from which the details of the device are made. If cast iron is used, then the mass of the tool reaches 2-3 kg.

What is

A manual drill and a columnor have a slightly different design, but the result as a result is the same. The moment of rotation of the collar cartridge directly depends on the number of rotational movements by a person. Hand drills are a single.Speed type, and two.Speed.

The manual two.Speed drill is equipped with four gears, through which an increase in torque is carried out when applying the force of one magnitude. This property allows you to adjust the speed of drilling holes, increasing it 2-4 times compared to the collar. To regulate the speed, it is necessary to simply change the shaft of the drive on which the handle is fixed.

Single.Speed drills are a simplified version, since they have 2 gears, one of which (large diameter) is a leading one, and the second led. In such tools, the speed of rotation of the cartridge can only be adjusted by hand.

Structurally hand tool is:

  • From two to four gears depending on the type of tool;
  • The handle that connects to the shaft of the lead gear;
  • A cartridge presented in the form of a zanovic mechanism;
  • Additional handle for holding the device;
  • Emphasis.

The principle of operation of a hand drill is quite simple. The leading gear is given in motion with the help of the handle, which is several times larger in size than the driven. A different number of teeth on the leading and driven gears allows you to change the torque. The gear moment provides the rotation of the driven gear, which is strictly connected to the cartridge of the tool.

Work with a hand drill

Working with a mechanical manual drill, it is important to follow the safety rules during operation. Such a tool is less dangerous than electric counterparts, but, nevertheless, you can cause irreparable health damage. When working with the device under consideration, it is important to follow the following recommendations:

  • The detail that is drilled, or into which the fastener element is screwed, must be securely fixed, otherwise you can cause damage to yourself.
  • The drill, as well as on power tools, has the ability to heat up when drilling, so do not rush to take it in the hand after the end of work.
  • During the drilling, it is important to give the drill to cool, since its excessive overheating can lead to dullness and damage.
  • When working with a tool, it is important to put on protective glasses and gloves.

Compliance with the simplest safety rules when working with a manual drill will eliminate serious injuries and damage.

How to do it with your own hands?

Finally, it remains to tell about the manufacture of the simplest hand drill on your own. The described method involves the use of an old umbrella, dowel and drill as the components of the created tool, as well as the simplest inventory. A hammer and hacksaw for metal. Practice shows that you can solve this problem in a few minutes, adhering to the algorithm below:

  • Take an umbrella and saw off a fragment of the required length from its rod (along with a handle);
  • Bend the workpiece in two places at an angle, as close as possible to straight;
  • Choose a dowel of suitable diameter and drive it into the pipe to the maximum possible depth, after which it is reliably fixed in it.

If the master needs a thiner cutting tool, he will need another dowel that needs to be driven into the already installed. Upon completion of this action, it remains to take a smaller diameter drill and fix it with the way described above.

Summing up, it can be stated that hand drills deservedly enjoy their popularity. It makes sense to use them who appreciates reliable and unpretentious tools that can provide high quality work performed.
