How to use a drill? Installing and removing the drill from the tool – Setafi

Electric drill - This is a tool designed for drilling holes in various rocks. The tool itself is not capable of drilling without a special nozzle - a drill. Therefore, to start using a drill, you need to know at least two useful things:

• how to insert a drill into a drill;
• how to remove a drill from a drill.

We will talk about this and not only in our article today.

How to insert a drill into a drill?

As noted above, a drill without a drill turns into a useless tool. It is thanks to the drills that the holes of the desired diameter and in the right place are obtained. Before inserting a drill into a drill, you need:

1. Choose the right drill.
2. Determine the mechanism for attaching the drill to the drill.

How to insert a drill into a drill: choose a drill

First you need to understand what you are going to drill. For different materials, you will need to look for the appropriate drill. For example, for wood they have their own drills, for metal they have their own, and for concrete, stone, brick - their own. Drills that come specifically for wood are not designed for drilling metal or concrete. Drills for concrete are not designed for drilling metal and wood. Metal drill bits are not designed to drill concrete, but they can drill through wood. Drills for concrete differ from other types of drills in a design feature, namely the presence of a special victorious tip. Drills for metal and wood may be similar in appearance and differ only in hardening, sharpening or coating. At the same time, there is a separate category of drills for wood, which have a “feather shape” - they are difficult to confuse with other drills.

The second point is the diameter of the drill. If you accidentally drill a hole with a slightly larger diameter, then it will be very difficult for you to correct the situation, and in some cases it will be impossible to do it. If the hole is a little smaller than necessary, then it's okay - just expand it with a slightly larger diameter drill.

The third point is the length of the drill. If you need to make several holes in thin material, then all you need to consider is that the length of the “working” part of the drill should be slightly longer than the thickness of the material. Another thing is when you need to drill a hole in depth. For example, you want to hang a picture on the wall or fix a cornice, a boiler, a wardrobe, etc. There are 2 things to consider here:

1. wall thickness. For example, if you want to hang a picture on a non-bearing wall 12 cm thick and for this you take a concrete drill 20 cm long, then there is a big risk that you will not guess the depth of the hole and drill through the wall, and there neighbour! In the end, you will have to do cosmetic repairs to your neighbor because of your carelessness.
2. Attachment length. For example, you want to hang a boiler on the wall and bought an anchor 12 cm long for it, but at the same time you have a drill of the required diameter for concrete, but 10 cm long. This means that the hole will not be deep enough and the anchor will not go in properly. As a result, it may simply not be aesthetically beautiful, but the mount may not work to “open up” inside the concrete and your boiler simply will not hold.

We will assume that you have correctly selected the drill for its purpose, diameter and length, now it's time to determine how to insert the drill into the drill.

How to insert a drill into a drill: fastening mechanism

You need to look around the drill with your eyes. There are only two options here:

• the mechanism can be using a key;
• the mechanism can be fast-clamping.

In the photo it looks like this:

The mechanism with a key implies the presence of a special device with which the drill is clamped in the drill chuck. Such a mechanism is quite simple to use:

• insert the drill into the drill chuck;
• insert a special key into the hole on the drill chuck;
• turn the key clockwise - the cartridge is clamped;
• turn the key with maximum hand force.

Here's how it looks in the photo:

Visually, the clamping mechanism with a key can be identified by the presence of special holes and teeth for the key on the drill chuck. Such a mechanism is convenient and clamps the drills quite tightly, but its main disadvantage is the key. If suddenly the key is lost, then it will be very difficult to insert or remove the drill from the drill.

Another thing is the quick-clamping mechanism. It doesn't need anything to work but your hand. The principle of operation of such a mechanism is as follows:

• insert the drill into the drill chuck;
• clamp the lock button, which blocks the scrolling of the cartridge;
• twist the cartridge by hand until it stops.

Here's how it looks in the photo:

Experienced drill users use this mechanism even more simply:

• insert the drill into the drill chuck;
• hold the cartridge by hand;
• start the drill by pressing the start button, holding the chuck until the drill is fully fixed.

This method is not recommended and correct, because it is pursued by a lot of risks, but nevertheless it is very popular with craftsmen who have been working with drills and screwdrivers with quick clamps for a long time. mechanisms.

How to remove a drill from a drill?

It’s probably easy to guess that it’s easy to remove a drill from a drill if you put it there. This process will depend entirely on the mechanism of the drill chuck. The difference will only be in the direction of rotation of the clamping key or keyless chuck.

However, even for this simple process, there are a few guidelines:

1. Power off the drill. If you want to release the drill with the "wrong" quick-release method, then you do not need to de-energize. Simply hold the chuck with your hand, switch the drill to "reverse" and smoothly press the "Start" button.
2. If you have just finished drilling and need to replace the drill, do not grab the drill itself, as it can be very hot.
3. It is not always possible to free the drill the first time - this is normal. If you worked with a drill for a long time, then the chuck automatically clamped very strongly and the clamping mechanism “got stuck” a little. You just need to put in more effort. For example, you can wrap the quick-clamping mechanism with a cloth to increase the coupling of the hand with the cartridge. You can lightly tap the cartridge. If the cartridge is with a key mechanism, then you can tap lightly with a hammer.
4. If the key to the clamping mechanism is lost, then you can use the gas key and some kind of latch. You need to insert the latch into the key hole in the chuck. The fixer can be a nail or screwdriver, suitable in diameter. Having fixed it, you can try to unscrew the cartridge with your hands, if it doesn’t work out, then the gas key will help you.

Conclusion

Now the questions: "How to insert a drill into a drill?" or “How do I remove a drill from a drill?” - will not put you in a dead end. A drill, although it seems like a simple tool, will nevertheless require skill and caution from you. Therefore, the first thing when working with a drill and even when changing drills, take care of your safety.
