The main thing you should know about an electric drill is that you can change the bits. Most modern electric drills have a wrench to tighten the chuck and fix the exercise. Is that how it works:
Loosen the mandrel: This piece (also called drill chuck) is located at the front end of the drill, and can be loosened and tightened to hold the drill bit. Remember: to the right to stretch and to the left to relax.
Remove the drill: Once you notice that the mandrel is loose and the drill starts to wobble.
Insert the new drill into the chuck: Do it so that its smooth part (rear part) is facing the mandrel. And make sure it is perfectly centered.
Tighten: Make sure the drill bit is firmly fixed. Many domestic drills use keyless chucks, which means they can be hand tightened; however, some drills require the use of a wrench to tighten the chuck. The wrench is usually stored at the top of the drill or in the handle.
It is essential to define the correct speed at which we are going to drill, and this will make a difference in drilling. We usually will increase the speed depending on the hardness of the material we are working on. It is advisable to start at a low speed.
Most drills have two speeds, but they can have up to three. Setting 1 is low speed and the best for screwing. Setting 2 is medium speed and can be used to drill harder surfaces. Setting 3 is the maximum speed and is used to drill hard surfaces or nail the screws. There is also a button near the trigger that tells the drill if it should move forward (clockwise) or rewind.
Do not adjust the speed switch unless the tool is completely stopped, or you can damage the gear.
Located just behind the chuck, the drill clutch or torque control is useful when tightening screws. The grip is essential not to damage the head of delicate screws or to prevent a screw from embedding more than the account where we are introducing it.
The mechanism works as follows: Once a predetermined resistance level has been reached, the clutch “disengages” the chuck of the cordless drill. The engine continues to run but does not transmit the movement to the chuck. To adjust the grip, align the arrow to a lower position, and begin to tighten the screw.
After the highest number in the clutch adjustment, an icon of a drill bit will appear. Place the arrow on this icon when you want to drill. If your drill is equipped with a hammer drill setting, you will also see a hammer icon. This adjustment will hook the hammer mechanism into the drill bit, which will strike behind the drill bit to aid in brick and masonry drilling.
Notice! Do not use any of these settings when screwing or fixing the screws. The drill does not need a clutch, which means that the chuck does not disengage but stops if it overloads, causing a sudden twist. This can cause serious injury to the wrist or hand.
Each drill has a forward and reverses power. It is a slide switch that indicates and changes the direction in which the drill is drilling, depending on the direction in which it is pressed. Usually, there are arrows on each side of the switch to help indicate the direction. By placing the switch in the center position, it will lock the tool. So if your battery is charged and you don’t understand why the drill does not work, then make sure it is placed forward or backward and not turned off.
