How to Remove a Drill from a Punch
How to insert a drill into a perforator? There’s an answer! All about drill rules
Drills are a tool used to make holes or recesses in any material. This process, called drilling, is carried out by rotating the cutting edge moving along the axis.
For comfortable work with brick, stone and concrete surfaces, samples with a hard tip made of a special alloy are used.
The tools used when drilling with a hammer drill can have either a cylindrical shank or an SDS form, which is distinguished by drills, which can also be divided into different types. This article will tell you about some principles of working with drills and the right choice of tool.
Work with drills
Before you start working with a punch, it is worth familiarizing yourself with how to handle drills in various situations.
How to insert a drill into a perforator?
Answering this question of how to insert a drill into a perforator, it should be mentioned that perforators are equipped with two types of cartridges. protracted with a key and keyless.
In the first case, the drill is clamped and removed by using a special key, in the second. it is fixed without using auxiliary tools. But first you need to correctly insert the cartridge itself into the punch, acting as follows:
- A bit of special grease is poured into the drill hole, where the cartridge will be inserted;
- The lower part of the punch body rests on a hard surface;
- The lower element of the head of the apparatus is pulled down;
- Insert the cartridge and release the lower element of the head, returning it to its original position.
The last thing you need to know is how to fix a drill in a punch. This is done simply: install the drill and clamp it, turning the top of the chuck (if using a quick-clamp mechanism), or tightening with a key (if working with a key chuck).
After installing the drill, you need to check the quality of its fixation. If it is loose, tighten the cartridge more firmly. Next, the device is connected to the mains and several times press the start button, thereby helping the lubricant to flow through all the details of the mechanism.
Getting started, set the desired mode and give the device a little work at idle. This allows you to make sure that the gearbox is functioning correctly, without unnecessary noise, knocking or vibration.
How to remove the drill from the punch?
If a key chuck is installed on the punch, then everything is simple. the drill is pulled out the same way as from a conventional drill, that is, by loosening the chuck with a key.
Before you pull out the tool from the double-coupled quick-clamping chuck, you need to switch the hammer to reverse mode
Then with one hand you need to clamp the lower sleeve, and with the other. unscrew the upper one. The drill can be removed from the one-foot cartridge with one hand, since such a mechanism is mounted on rotary hammers with automatic shaft locking.
How to get a stuck drill in a hammer drill?
Drill stuck in a punch? How to get it from there and what to do depends on the situation, which can be exactly three:
- The drill is clamped in a chuck or adapter for using a conventional drill in a hammer drill;
- The drill bit jammed in the perforating cartridge;
- The tool is stuck in the wall.
The first situation is typical for those cases when the punch is used as a conventional drill, using an installed chuck. It happens that after carrying out drilling work, the drill cannot be pulled out of the cartridge, as it is too tightened and does not unscrew. This happens mainly due to lack of lubrication in the clamp or when clogging occurs in it.
To unclean the cartridge, it must be treated with a special WD-40 grease or kerosene. After 10-15 minutes you should lightly tap the cartridge while trying to loosen the stuck tool. After that, the clamp is usually easily untwisted.
A completely different situation arises when the drill is jammed in the drill chuck. In the process of shock or reverse-shock movements of the drill, its shank (in the case of using a cheap tool made of non-hardened steel) can rivet. As a result, it gets stuck in the trunk. How to remove the drill from the punch. consider step by step:
- The drill is fixed in a vice, after which the punch is slightly loosened and pulled onto itself;
- They fix the puncher in a large vice, grab the drill itself with a pipe wrench and beat it with a hammer, thus pulling out the stuck tool.
When jamming the drill due to turning in the clamp, you need to disassemble the chuck by removing the cap and rubber ring, or try to turn the drill 90 degrees back.
If the shank is severely deformed, it will not work to pull out the drill in the considered ways. In this case, you will have to completely disassemble the punch, and then knock out the stuck drill.
Now, as for the case when the drill is stuck in the wall. If this happens, you should not continue to press the start button and try to loosen the hammer with your hands. So you can only break the drill, or even completely burn the device.
Instead, you need to carefully release the drill from the drill and insert another into it. Next, drill concrete around the stuck element, after which it will be possible to pull it out quietly.
One of the most common problems encountered with a hammer drill. SDS drill stuck. The video shows how to solve this problem.
For high-quality, convenient and correct operation, you should know which drills are best used and how to choose them.
Today, these tools are made of high speed, carbon and alloy steels. When working with highly hard materials, products with victorious brazed ends should be used.
Special attention should be paid to the choice of Boers. This tool can be divided into two large groups:
- SDS Plus. used when working with a light and medium type tool for drilling holes of small diameter (from 5mm to 32mm);
- SDS Max. for larger machines (drill diameter can range from 16 to 50 mm).
When choosing a drill, you should focus primarily on prices. cheaper samples will have appropriate quality. For a long time such a tool is not enough. In addition, it is worth paying attention to the appearance of the Boers. High-quality products have strictly sustained dimensions, as well as a clear geometry of the grooves and recesses located on the shank.
If you plan to drill large holes, for example, for a socket or switch, then special crowns are needed here. With their help, you can drill holes with a diameter of 35 to 120 mm. For the socket, a crown with a diameter of 68 mm is used.
It should be remembered that not only the quality of the work performed, but also the life of the drill, depends on the correct choice of the drill, as well as the skillful handling of the tool.
How to get a drill from a perforator?
Nowadays, when building robots, you can no longer do without a punch. Using it, you can drill any hole, as well as dismantle the wall or ceiling. Often there is a situation when the drill is stuck in the chuck and it is very difficult or impossible to pull it out. How to pull out the drill yourself? To understand this you need to know the reasons for the emergence of such an urgent problem.
- How to disassemble a punch
- Punch Cartridge Device
There are two varieties of this problem:
- Either the drill stuck in the drill chuck or adapter chuck for operating a simple drill in a hammer drill;
- stuck a drill in a perforating cartridge.
The first version of events happens at a time when you need to use a hammer drill as an ordinary drill. In these cases, a transitional chuck is used, the same as in an ordinary drill, it is mounted in the perforator clamp, and then the drilling process is carried out. After completing the required work, it is sometimes simply impossible to calmly pull out the drill, because the chuck is so long that it cannot be unscrewed. This mainly happens when the clamp was not lubricated or clogged.
In order for it to unclench, it is enough to treat it with WD-40, or use kerosene. After some time, you need to tap the cartridge a little while trying to shake the drill with the other hand. After that, the clamp should loosen easily. After this, the empty cartridge must be cleaned and greased.
It’s a completely different matter if the drill is stuck in a perforating cartridge. This does not happen at all, as in the first embodiment. A drill or drill in a drill only feels twisting and occasionally small shock loads, which extend to them only through clamping jaws and continuous emphasis in the bottom of the cartridge. In a punch, a completely different mechanism for transmitting stresses and absolutely no such kinematics of the drill in the chuck. All because it involves the reverse-shock or shock direction of transmission of stresses. Devices take energy from a special hammer, which runs on an electric motor and hits their shank. On the surface of the devices are the so-called grooves, with which they are fixed in the cartridge and can withstand a reasonable load. For cheap tools, steel is used that did not pass hardening, because of this, a shank can rivet in the puncher during prolonged operation.
Ways That Can Help Pull out the Drill (Video)
The punch holder is arranged so that during operation, drilling or drilling equipment moves along the barrel. During riveting, the barrel will not allow the drill to exit easily. You can try to get a drill in the following ways:
Видео: How to Remove a Drill from a Punch
- It is necessary to clamp the drill in a vice and then slowly loosen the hammer to pull it onto you.
- In large tees, the punch itself is clamped, but so as not to cause damage to the body. Then the drill is clamped with a pipe wrench or in a small vise, and then you need to beat them with a hammer while knocking out a drill.
In any of these cases, a few drops of WD-40 will not be superfluous. Very rarely, the drill bit wedges due to the lack of lubrication or clogged cartridge. The fixation ball, in cases where a foreign body is under it, will not allow the drill to exit. To avoid this, it is necessary that the shank on the device is always lubricated.
If the drill got stuck due to the fact that it turned in the chuck, then you need to remove the chuck itself, while dismantling the cap and rubber ring, or try to turn it back 90 °. Because of this, most likely, you will have to replace all the clamping parts on the punch.
But do not forget that if the shank is already broken, it will not work to free the drill. In this case, you need to completely disassemble the punch and already, then knock out the stuck fixture. But again, after such maneuvers, the barrel will need to be replaced.
Recommendations for preventing such cases
When using high-quality drills, the drill in the hammer will never get stuck. But at the same time, you need to beware of fakes, since at the moment there are a lot of them. And in order to prevent such excesses, it is advised to conduct trial work with the purchased device.
There are cases when holes in materials for which the inserted drill is not suitable are made a powerful punch. And then even a high-quality drill will not withstand such loads and rivet.
How to use a drill: change the drill, drill tiles, metal and other materials
The drill acquired its modern look in the middle of the second decade of the last century, when two mechanics from Maryland, USA, decided to give it the appearance of a gun with a trigger button instead of a trigger. Today, this tool takes a leading place in any construction, a wide variety of nozzles make it universal and indispensable. But so far, many users do not know how to use the drill properly. this article will help you find the answer.
Purpose of use
The main purpose of any drill is to drill holes in various materials, so all the calculations of the developers of new models of this practical tool are aimed at improving the quality of drilling. The tool has several speeds, for this a gear is used, which connects the electric motor to the working shaft. How the gearbox works: by changing the gear ratio of the gearbox, we increase or decrease the speed of rotation of the cutting tool.
Modern drills have 2 operating modes.
- Simple drilling is used when working with wood, tiles.
- Hammer drilling is used when drilling particularly strong materials: walls made of stone or brick, concrete structures, thick metal.
For such drilling, special drills are used that have hard alloys at the end. To make the drilling process faster, a force of up to 15 kg must be applied to the tool body.
Simple drills of mechanics of service stations are very often used for high-quality polishing of a car or after painting a car, so that the paint looks spectacular. Drill polishing of various surfaces is also carried out during home repairs.
Preparation for operation
Experts note the readiness of the tool for subsequent work on the following grounds
- the product is plugged in. this applies to a drill that is powered by an electrical network;
- the battery is charged and inserted into the bottom of the device. this applies to a stand-alone tool with batteries;
- the necessary nozzle is installed in the cartridge.
Important! In order for the drilling to be smooth and the edges to be smooth, the cutting surface must be sharpened on emery before work.
Then, you need to correctly insert the drill into the drill. many users do not know some of the nuances. The hole where the drill is inserted has a depth of only 2 cm, and that the drill rotates smoothly and without beating, it must be accurately fixed. The clamping mechanisms in this tool are of two types:
- manual, when tightening is done manually;
- mechanical. fixing the jaw of the cartridge occurs with a special key.
The initial installation of the drill is carried out in stages.
- We turn the cartridge until the jaws are separated by a little more than the diameter of the inserted or replaced drill.
- Install the drill into the hole formed until it stops.
- Gently twist the chuck and make sure that the drill shank is clamped evenly.
- Then tighten the cartridge with your hands or a key.
When manually tightening, remember that after work, the drill will need to be pulled out of the chuck, so do not use excessive force.
To change the drill in the drill, you must first completely stop the chuck. Do not brake it with your hands. you risk getting a temperature injury. To properly remove the drill from the drill, you need to perform several simple steps, strictly following the order. If you have a drill with a keyless chuck, then the following procedure should be followed.
- Remove finger from start button.
- After stopping the rotor, hold the lower part of the cartridge with your left hand and turn the upper part counterclockwise with your right hand.
- As a result of your actions, the cams of the mechanism will open, and you can remove the drill.
When the tool is mechanically tightened, perform the following actions:
- insert a key;
- rotate it to loosen the jaw clamp;
- Next, unscrew the chuck by hand and remove the drill.
To keep the key always near the drill and not get lost. fasten it on a special carbine to the power cord, as shown in the photo.
A drill is a very powerful tool and is considered source of danger, so when it is used, simple rules must be followed.
- The workpiece in which you decided to drill a hole must be clamped in a vice. In no case do not try to hold it with your hands. you may get injured.
- Clamp the cutting tool or tool in the chuck tightly, check how it holds before turning on the tool.
- When working with particularly hard materials, the drill must be held with both hands and constant pressure is applied to increase the effect of drilling.
- Pressure must be done without fanaticism so that the working tool does not jam in the hole, especially when you drill large diameter holes. The pressure must be reduced when the cutting tool exits from the back of the workpiece.
- Be sure to use gloves and glasses.
- Switching of operating modes and replacement of nozzles must be carried out only after complete cessation of rotation.
- Clean metal chips and other drilling waste with a brush only.
In the enlarged freeze frame, the smallest fragments are clearly visible, which can injure the unprotected hands of the unfortunate master.
Drill various holes
Sometimes during repair there is a need to drill holes at different angles and in different planes, this can be done in such ways.
Vertical and horizontal planes:
- pre-mark the drilling location;
- to fix a drill in the product cartridge;
- bring the drill to the drilling site;
- gently press the button and lightly press on the device;
- make sure that the drill is in the correct plane at the intended hole, then continue drilling;
- pull out the drill without turning off the tool;
- wait for the rotating cartridge to stop;
- set the drill aside.
When you need to drill a perpendicular hole with a drill, and the angle of 90 degrees should be perfect, you should use a special clamp. The tool is fixed strictly vertically. this is suitable for beginners. For experienced home-made craftsmen, the original method is suitable:
- we put the old compact disc in the place of drilling;
- align the cutting tool so that its visible part fully coincides with the reflection in the mirror surface of the disc;
- we drill a hole that will be perpendicular without any goniometers.
When it is necessary to drill an exact hole at an angle, then you can use the stand of the original design, shown in the photo below. Using it is simple: tighten the latches at the desired angle, insert a drill and drill any holes.
Drilling different materials
To drill a metal surface efficiently and quickly, you need to choose the right drill. sharpening of the cutting edge is significantly different, like the grade of steel of which the cutting tool is made. During operation, it is necessary to set low revolutions, and the pressure should be strong, but such that the drill does not break. The location of the proposed drilling is marked with a core drill. It is necessary to make a small depression so that the drill firmly hooks on the metal and does not "walk" on its surface.
When drilling concrete or brick, you must turn on shock mode and be sure to use a respirator, because there will be a lot of dust.
In order to drill tiles, some craftsmen use a thin wooden plank. We mark the place of the hole on the tile, then we put the wooden gasket and carefully drill it so that the delicate surface does not crack. This method can be used to drill the tile in the bathroom or in the kitchen, set the maximum speed on the drill.
When you need to make large holes in the tree, then use drills with a diameter thicker or special nozzles. Some experts use a powerful, but with low revolutions (not more than 600 rpm) drill for twisting screw piles on a personal plot. Installation is carried out by the method of gradual indentation into the soil with simultaneous screwing of the pile structure assembled in advance, using special wrenches of various diameters.
How to pull a drill out of a drill
How to pull a drill out of a drill
Greetings to all in the next article! When operating a particular device, the user sometimes encounters unpleasant moments. Today I will touch on one of them. In this text, I decided to give some tips on how to get the drill out of the drill, if you can’t do it. The reasons why it is not possible to do this seemingly simple thing can be very different. Here I described the main aspects on this topic and identified three main areas that I consider it necessary to disclose:
- replacement of a drill in a normally working chuck;
- pulling out a drill without a key;
- Removing a drill that is stuck due to some kind of existing damage.
We consider each of these circumstances separately.
How to remove a drill with a working cartridge
If everything is working properly, then there shouldn’t be any problems with getting it. Therefore, this section is more likely devoted to completely ignorant users of a power tool, since the operation itself is elementary. But still there are a lot of people, so maybe someone will need this information.
In this situation, you will need a special key to unlock the key cartridge, or straight arms to relax its quick-tight analogue.
In the first case, you need to insert the key into one of the recesses on the cartridge, and begin to rotate it counterclockwise. Promotion is due to the existing teeth on both items.
In the second, the drill should be included in the reverse (reverse rotation) mode. With one hand we hold the external case of the cartridge, and with the other we press the start button. If your machine is not equipped with a reverse, then this is not very good. this generally should not be, since only key cartridges are put on such devices. But still, if this happened, then you need to somehow fix the axis of the drill (for example, with an open-end wrench) and rotate the outer case of the chuck counterclockwise. In general, here it would be better to remove such a cartridge and put the key.
How to change a drill without a key in a drill
As you can see from the subtitle, here we are talking about key cartridges.
The most common method is the use of a Phillips screwdriver or nail of a suitable diameter, which is inserted into any of the existing recesses on the cartridge, thereby fixing its first half. You can try to twist the other half by hand. Usually in this way it is quite easy to spin.
However, if this does not work out, then you can use a gas key or a vice instead of a hand. Using them, you will be able to create the necessary effort, which is likely to be enough to carry out the rotation.
If you still don’t succeed as a result of these steps, try what is described in the next section.
How to get a drill from a damaged cartridge
Here we will also talk about cases where the drill itself is damaged.
Damage is usually in the form of a broken cam or damaged thread. It also happens that the drill is damaged, for example, scrolling between the cams. As a result of this, shavings are formed that interfere with normal rotation, as it clogs into different slots, which prevents rotation.
So, for starters, you can try to relax the fists. This can be done again with the help of two gas keys or one in assistance with a vise.
In the first case, each part of the cartridge is clamped with its own key and rotation is performed on loosening. In the second, fixing one of the parts is no longer carried out with a key, but with a vise. Since this creates a fairly large effort, the unlocking is quite easy.
In addition, in the absence of a gas key, one part can be clamped in a vise, and the second one can be used to apply gentle blows with a hammer along the tangent. Relaxation is due to the generated vibration.
If the previous methods do not help, for example, due to the thread being broken on the cams, you will have to resort to the next point.
First you will need to twist the cartridge with an electric drill. How to accomplish this, I have already described on this page. Then we clamp it in a vice and knock out the drill from the inside with a punch of a suitable diameter, which is threaded through the hole into which the spindle is inserted.
That’s all. These are the main solutions that can be applied if you need to pull the drill out of the drill. As you can see, everything is very simple. Of course, in special cases, different devices may be required, although most of the home masters have the ones that I described. Hope my tips help you. I wish you no longer have such problems. See you soon!
