How to Fix a Drill In a Keyless Drill
In any living room, sooner or later a situation arises when you need to redo something: hang a picture, screw the shelves or make wiring. But most concrete and brick walls cannot be pierced with a nail just like that, and you cannot screw a screw into them. Therefore, you have to resort to the use of electric drill. This is a convenient device that allows you to make a hole of the required diameter in the wall due to the variety of drills: on concrete, metal, glass, plastic, tile or wood. But for the successful use of an electric drill, you should know the basic rules of use with this tool.
Subtleties of operation
Electric drills began to appear at the end of the 19th century almost immediately after the invention of electric motors. The main objective of a tool with a percussion mechanism, which was introduced into production, was to drill various holes in materials using electricity and high speed drill bits.
Already from the description it is clear: in order to use such a tool, you need to follow certain safety rules.
- Before starting work, it is necessary to inspect: a drill so that there are no open electronic (current-carrying) parts; the wire going to the network so that it is not damaged; a fork so that it is solid and working; socket so that it is in good working order and fits tightly in the wall. In this case, the plug should fit snugly into the socket and there should be no sparks.
- Insert the drill into the drill as tightly as possible.
- Select the required mode: drilling (torsion of the drill at a high speed) or drilling (drilling using a percussion mechanism).
- Select the ultimate torsion speed of the drill.
- After making a hole of the desired diameter and length, you should press the power button, and then remove the plug from the outlet, so as not to accidentally start the tool when not required.
It is worth noting that there are functional drills that recognize the diameter of the drill, have limiters to fix the desired drilling depth, have handles for greater fixation of the tool in the hand, and automatically change the drilling speed. Such functional drills require additional settings so that the automation does not fail at the most inopportune moment.
Drills are selected in accordance with the requirements for the work. But you must remember that they are different, and some drills are not suitable for one or another drill.
Here the main role is played by the tool holder, which happens:
The first option implies that the user has a special key with which you can loosen the cartridge. To do this, use the hole on the drill and turn the key counterclockwise or turn it clockwise, and thus clamp it. Often this key is attached to the drill, which reduces the likelihood of its loss and allows you to remove the key from the mount at any time and use it.
The second option is something else, because a quick-clamping can be:
If you use a one-foot cartridge, you only need one hand to grip, and the second option is a bit more complicated: you have to clamp one clutch, and with the other hand, twist the other clutch. Both options save time, but the fixation is much worse than when using a key cartridge.
How to insert a drill into a drill?
This operation is simple and quick, but some rules must be followed. A step-by-step instruction will protect you while placing the drill in the drill.
- Disconnect the tool from the network.
- Then choose a suitable drill, taking into account the nature of the work, the material in which the hole will be made and the compatibility of the drill with the drill.
- Place the drill in the chuck with the tail part inward (“shank”).
- Then you should fix the cartridge, given its appearance. If the key, then fasten with a special key with teeth, if quick-clamp, then fasten with your hands.
- After the drill is locked, make sure that it does not stagger in the chuck and there is no backlash.
- Then you can get to work.
It is worth noting that the choice of drills depends on your electric drill. There are various models with a variety of technical equipment and features. Some drills cannot be used, for example, for metal work. Others. Allow the installation of drills in diameter from 0.8 to 10 mm or from 1.5 to 13 mm. It is not recommended to buy cheap drills made of low-quality metal, it is better to overpay, but make sure that the tool works properly and for a long time.
How to pull a drill out of a drill?
If you need to change the drill, which has become unusable, or due to a change in the nature of the work, you need to set another, then the process is even simpler than when setting the drill.
There is also a step-by-step instruction for this case.
- Switch off and disconnect the power drill.
- Depending on the cartridge, use the key or turn the clutch by turning it counterclockwise, thereby loosening the cartridge. Try not to tackle the drill, because after work it may remain hot for a while.
- Having removed the previous drill from the cartridge, change it to another and continue working or remove the tool for storage.
If you can’t turn the cartridge the first time, don’t rush to the workshops, most often it’s enough to just put in more effort.
