How to choose a drill for a home.Couplings and recommendations with a photo

Than to drill a hole in a tree, brick or concrete? Which drill is better for the home: shock or unstressed, network or battery, professional or household? What else can be done using a drill? You can find answers to these and other questions in our article.

Which drill to choose for home

  • Hang a picture, hanger or some other interior item.
  • Adjust the sagging interior door or door in the closet.
  • Fix something with self-tapping screws.
  • Punch through the wall in the wall.

Almost any person invariably encounters these and other household tasks. To fulfill them quickly and efficiently, just use the electric drill. This is one of those tools that should be in every apartment along with a hammer and a screwdriver. But which drill to choose for home? In order to correctly answer this question, you need to know the varieties and the possibilities of this power tool and clearly imagine why it may be required specifically.

What are the drills

Depending on the design features and purpose, the following types of drills can be distinguished:

Unstressed drill. Designed to make holes in relatively soft materials: wood, plastic, drywall and metal of small thickness. It is suitable for small repair of various products and fix objects on partitions from soft materials.

Shock drill. With its help you can additionally drill brick, concrete walls and ceilings. If you need to hang a chandelier or cabinet, make a hole in the floor or ceiling, install the doors, then it is precisely it. When the shock mode is turned on, its cartridge makes reciprocating, directed perpendicular to its own axis of rotation. This allows the drill to quickly make your way even in solid material.

Corner drill. Equipped with a cartridge located at right angles to the handle, and can be used in hard.To.Reach places. It will help in cases where holes must be done in a narrow niche and an opening, space occupied by any objects.

Drill Mixer-intended primarily for mixing various solutions and paintwork materials. Some models are also suitable for drilling holes of large diameter and surface cleaning, for example, from paint and rust.

In most cases, it is better to choose a shock drill or drill-shuruvret drill. The advantage of the latter is that it additionally allows you to tighten and unscrew the screws and screws, that is, it is a more multifunctional tool. Unlike the rest, the drill-shuruver always has a reverse-its cartridge can rotate clockwise and counterclockwise, as well as multi-stage adjustment of the torque.

Which drill to buy: household or professional

All drills can be divided into household drills and professional drills. The difference between them is that the model intended for professional application is designed for more serious loads and intensive use. Conventionally, they must work out during the service life, provided that daily use for several hours in a row. This is ensured by the use of wear.Resistant materials and characteristic design features.

The design of household drills is usually easier, and the details are more susceptible to wear. However, their cost is also significantly lower. Thus, if the task is to buy a home drill, which will be used often and will last several years, it is better to choose a professional model. If you plan to get a tool from a box every few months, then you can buy a cheaper household tool.

What power should be at the drill for the house

The power of the drill, or rather its engine, is one of its main parameters that directly affect the speed of rotation and torque, and therefore on performance and functionality. A powerful tool breaks the hole faster even in solid materials, at the same time it is more expensive and has more weight.

Unstressed usually have a capacity of 250 to 500 watts, drums-from 500 to 1500 watts, mixers drills from 800 to 2000 watts. If you plan to use an electric drill exclusively to drill small holes in wooden and plastic products, then there is no particular need to buy a tool more powerful than 600 watts. For effective drilling brick and holes with a diameter of more than 10 mm, the power should be from 800 watts and above, and if you plan to pierce concrete walls and mix building mixtures, then the power is at least 1 kW.

What does the speed of rotation and torque affect

Rotational speed. This is the number of revolutions made by the cartridge per unit time. The higher it is, the faster the hole forms. To work with wood or plastic, this parameter is not so critical, but if you plan to drill metal, glass, ceramic tiles and even more concrete, it is better to buy a drill that has a rotation speed of at least 3000 rpm.

Most modern models are equipped with an electronic rotation speed regulator. The stronger the user presses the button on the handle that starts the tool, the faster the cartridge moves. Some also have a switch that allows you to limit the number of revolutions, since you need a low speed to tighten and unscrew the fasteners.

Before choosing a drill-shuruvret, you should pay more attention to another parameter-the maximum torque. It is its value that determines the force with which the tool will affect the fasteners. Ideally, torque should be at least 30 nm, otherwise it will not be possible to screw screws into products made of solid materials without preliminary drilling.

What cartridge should be in the drill for the house

Professional and domestic electrodels are equipped with two types of cartridges: fast.Packed and gear.

Drinks with a fast.Packed cartridge are more convenient, since replacing a drill or bit does not require the use of an additional tool. This can be done manually. If it is planned to work mainly with various soft materials and often change the equipment, it is better to choose a drill with a fast.Packed cartridge.

Installation of torque

The drill has a control ring to install the torque at which its values ​​are applied.

This is necessary in order to set the most suitable value when working with materials that have different hardness.

For example, for twisting screws into drywall (with a slight effort), a range of values ​​2-4 is suitable, and for a hard tree, the torque can be set to the maximum number on the ring.

Such adjustment helps to avoid quick damage to the fasteners of fasteners.

Trigger drill

Trigger or, as it is also called, the start button is, in principle, a very simple organ. He launches the device or stops it. To do this, accordingly, you must click on it or release it.

However, with a trigger there is one nuance. Because in separate models by force of pressing the trigger you can change the speed of rotation.

What is the screwdriver consists of? Settings of the device.

In the plastic case there is a engine and a geover mechanism that drives the bat, which is installed at the end of the screwdriver. The device is provided for by the presence of a start.Up starter, direction of direction and speed speed, diode illumination and tightening time regulator.

The principle of activity of the tool is very simple. The nozzle, previously fixed in the cartridge, moves using a shaft, which starts moving from the work of the motor through the gearbox. Before using a screwdriver, you should find out if the battery is charged, and whether the nozzle is installed correctly.

Immediately before the work, you need to look after such a nozzle so that it corresponds to the self.Tapping screw or screw hat.

To install the desired nozzle, you should choose it by the size of the hat of the fastener and fix it in the magnetic holder of the cartridge. First, the cartridge with the coupling must be removed from the device, and after fixing the bat, the cartridge must again be fixed to the screwdriver body.

Then it is required to assign a suitable bit speed of the bit. Settings are performed by means of a special regulator. The required mode is set in the disconnected state of the tool.

Before using the power tool, it is necessary to adjust the depth of screwing the fastening element. After some time, the need to replace the magnetic holder may arise. To change it, a cartridge, magnetic mount and coupling is removed. Next, the cartridge with the coupling is fixed back to the block-the-clock of the screwdriver.

Communities Tool. We share experience Forum Selection of a screwdriver

Hello, and again I’m with the choice of a screwdriver. I decided to buy Shurik from the budget line all the same., with some models, but I still don’t know anything about them.Maybe someone had experience with these models, manufacturers, share your experience and knowledge about them.Edon CF 1202, Patriot BK 114 Li, Einhell Th-Co 12-2 Li, Bort BAB-10.8 NX2LI-FDK.

I believe that overwhelming money and take the Chinese on lithium-ion batteries 14.4V with a good torque.

You can advise such a shurik, the main thing is not to be particularly bulky?

I would advise Makita, good equipment and the most important presence of spare parts and this is the most important thing when choosing.

I am familiar with Einchell from these vehicles, a good Chin German, but now I work at the Poles factory, we repair refrigeration equipment, we have a good screwdriver, you can do it, and it continues to turn it out, but it continues to twist. True, they are nickel-cadmium, therefore should be taken with two batteries, or buy another, there is an effect of memory. They are charged quickly (somewhere around two hours)

Here’s the question, for what purposes it is. If in order to lie at home just in case, unscrew a dozen screws once a month, then it is not needed, it is better to buy a network drill with a screwdriver function. At home there is Energomash, 18 volts, the batteries died at a statute of limitations, and the question is that the purchase of two new batteries at a price is equal to the purchase of one new semi-professional drill-spray from the network. He did not work with my.

It is not necessary to take a screwdriver for the home, it can look towards the battery boot? Their power is enough for the house for the eyes.

The use of screwdriver

Those models of screwdrivers that are sold today in stores allow you to choose a bit to a self.Tapping screw so that their fit to each other is dense. And setting a screwdriver so that the delay of each self.Tribunal is perfect, it became very simple.

We Ranked Every DRILL/DRIVER From Beginner LVL To Expert LVL (What Level Are You?)

Do not think that you can use the screwdrivers, only to drill, twist and twist screws. When repairing a car, you can twist and twist nuts and bolts, grind a variety of surface nozzles. Assembly of furniture without using a screwdriver will take a lot of time. Hanging cornices for curtains or book shelves with a screwdriver is much easier than running with a screwdriver and making efforts. So today Shurovyrt has taken its honorable place among the most necessary tools in the household.

Proper use of a screwdriver

The screwdriver successfully replaced not only various types of screwdrivers, but also warden, hexagonal keys. This tool is also used instead of a drill. For builders with furniturers, the electric shuruvrustrot has become an indispensable assistant. For him and at home, there is constantly application. The assortment in the market is represented by a wide variety of models. Despite the prevalence of screwdrivers in various fields of activity, not all users, especially beginners, know how to operate it. Proper use, maintenance and storage of power tools will extend its service life to the maximum.

According to the power method, screwdrivers are divided into two varieties:

The external and internally device of network and battery models is almost the same. In general, the power tool consists of the following structural elements:

  • Hulls;
  • Cartridge;
  • Turning buttons;
  • Switch of the direction of rotation of the electric motor (reverse);
  • Speed regulator (number of revolutions);
  • Buttons of turning on on;
  • A tightening power regulator (switch of torque).

The photo further presents the design of the battery.Type screwdriver.

A number of models are additionally Equipped with backlight, which is constructively realized in different ways. Not every product has a speed control and button for turning on on. Network electric shuruvrusts have a power cord, and the battery has a charge drive instead of it.

The housing of the power tool Most often made of plastic, much less often from alloys of different metals. For convenience, it usually consists of 2 halves. There are such main details inside the case:

The circuit of electrical connections depends on the model.

Electric shurubover can be equipped with cartridges of different types. The most widespread Quick.Packed three.Cub variant of this part. The cartridge also consists of separate parts that are presented in the following photo.

Printing work both network and battery screwdrivers are the same. It lies in the fact that electric energy leads to rotation of the electric motor. Through the gearbox and the shaft, the force and speed to the nozzle fixed in the cartridge are transmitted from the motor. It already drills a hole or screws or twists fasteners. A feature of the process is that the electric motor in network models operates at a variable voltage of 220 V, and in battery ones. On a constant one, the value of which can be in the range from 3.5 v to 36 V 36 V.

Installation of torque

The drill has an adjusting ring for installing the torque for which its value is applied.

This is necessary in order to set the most suitable value when working with materials of various hardness.

For example, for screwing screws into drywall (with slight efforts), a range of values ​​2-4 is suitable, and for solid wood, the torque can be set on the maximum number on the ring.

drill, screwdriver, pros, cons

This regulation helps to avoid Rapid damage to the hairpins.

During operation, you can change the speed of rotation by increasing or decreasing the pressure on the trigger of the tool.

This allows you to stop the tool in time when the screw or screw is completely tightened.

Tool care

Squad, like any power tool, does not tolerate water, so it is better to use it away from moist places. Do not throw a tool or lay it carelessly. This can lead to damage to the details and its failure. It is necessary to try to avoid dust and dirt inward. Small.Dispersed particles can lead to an early breakdown of the device.

  • You should always work in gloves and goggles to avoid wounding with fragments.
  • You can not use damaged batteries and a tool with defects in the case.
  • Store the tool in a dry warm place protected from children.
  • Before starting work, you should check the performance and integrity of the device.

It must be remembered that the turning direction can only be changed when the electric motor is completely stopped.

If necessary, the cartridge of the drill-shurubound can be replaced. It must be borne in mind that it is fixed with a screw with left thread and it means you need to unscrew it clockwise.

drill, screwdriver, pros, cons

Access to this screw can be obtained through the front of the cartridge.

The instrumental kit also includes a set of drills of different diameters. All of them are designed to work in relatively soft materials.

Drills in the cartridge are clamped similarly to a nozzle with a bat.(cm. Photo above)

How to correctly change the drill or bit by screwdriver

Cartridge. A node of a screwdriver in which a shift nozzle is installed: a bat, drill or another. Installation is performed manually, automatically (without equipment) or with equipment in the form of a key. There are several types of cartridges.

How to correctly change the drill or bit in a screwdriver

The procedure for installing a change of nozzle is as follows:

The cams are compressed, for which the front coupling rotates counterclockwise. The nozzle is installed, the coupling is twisted back.

The nozzle is inserted or pulled out with a slight effort. Fixing the nozzle is performed by an attractive magnetic effect.

Most often used in screwdrivers with pneumatic drive. The head is executed in the direction of the opposite work direction. After installing the nozzle, the head is released, as a result of which the nozzle is fixed. In order to get it, you need to release the squeezing and holding of the head.

If the key is used for installation, then the process is as follows:

  • The spindle or engine is blocked, or the head with the nozzle is simply held by the hand;
  • By rotating the key installed in the groove, the cartridge is rotated before the tsang or the release of the nozzle;
  • The cartridge closes with the key in the opposite direction.

Regardless of the type of cartridge, you should pay attention to the position of the nozzle after installation. You need to serve food and start rotating the cartridge. If the nozzle is incorrectly installed, a beating will appear. The phenomenon of moving the end of the nozzle to the direction of rotation. In this mode, the work will not be effective.

How to use a battery

The power supply of battery models is Nickel-Kadmieva (Ni-CD) or Lithuanian (Li-Ion) battery. To understand how to work with a screwdriver with a first type of battery, you need to know the pros and cons of the latter.

The advantages include a low price, a large number of charge-discharge cycles, and the possibility of operation at low temperatures. Disadvantages release a loss of 8-10% of the container during storage, the “memory effect”. With each charging not a completely discharged power source, its capacity will gradually decrease. If the battery does not operate for a long time, then it will be ready to work after 5 charge-discharge cycles.

Lithium-ion samples attract the lack of “memory effect”. They can be charged with any degree of discharge. The advantages include low weight, low level of self.Discharge (up to 5% per month), charging speed. The main disadvantages highlight a high price and a quick discharge at a temperature below 0 degrees. Store such batteries with half a charge level.

How to use a drill-spacer on the battery, described in detail in the instructions for the operation of the unit. Even the most expensive models can work on one charge no more than 2 hours, so many manufacturers are equipped with a tool with a spare power source.

The battery is charged using a conventional or pulse charger. The rate of replenishment of the container in the first case is 2-6 hours, in the second-not more than 1.5 hours. Some models have fast charging. 30 minutes. When connected by the battery to the charger, you need to control the correctness of combination of polarity on each subject. The glow of the red LED indicates the beginning of the charge process, the ending of the green.

Tips for women on working with a screwdriver

Not always attach or unscrew the fasteners in the house, a man can. Interest on how to use a screwdriver often occurs in women. First of all, experts recommend choosing an easy and compact model.

Then you need to familiarize yourself with the instructions that describe how to twist the fasteners in materials of different densities in order to achieve the desired result. Having studied the rules for setting, installing nozzles, a woman should not forget that the use of the unit requires physical strength. When working, it is better to hold the tool with both hands and be extremely attentive.

Do not forget about the safety rules:

  • Start work only after setting up the unit and install the correct nozzle;
  • Avoid the flow of fluid, sand, building dust and shavings inside the body;
  • Perform operations in the room with good illumination;
  • Periodically clean and lubricate the cartridge;
  • Put on work clothes and protective glasses.

Features of proper storage in order to increase the service life

Knowing how the screwdrivers of the network and battery type work, it remains to understand the question of how to care for them to extend the service life. Everything is as simple as the principle of work of the screwdriver. The following recommendations are taken into account during storage:

  • Eliminate water entering the instrument
  • You can not miss and drop the device, since in addition to damage to the case, internal devices may come out of the system
  • Ensure regular patron lubrication to increase its service life
  • If different contaminants get inside, then before the subsequent use of the device, it should be disassembled and cleaned
  • You can not store the tool with completely batteries discharged
  • Store and operate the device in a temperature range of at least.5 and not higher than 30 degrees
  • When drilling, cool the nozzle

Only if all of the above recommendations are observed, it is possible to provide prolonged use of the tool without breakdowns. The service life of the device also depends on the quality, since the cheap Chinese screwdriver will not be able to last a long time a priori, because in its production exceptionally low quality components are used.

Summing up, it is worth noting that not only the master, whose work is related to the operation of the device, but also beginners who use the tool for the first time, should know about how the screwdriver works. This will extend the service life of a screwdriver, and also eliminate the need to pass the device to the service center, in case of malfunctions.
