Battery driven drill. I prefer this kind for everyday use. For heavy duty jobs though, the stronger drills with wires are usually required.
This is the forward/reverse switch. It goes all the way through the machine. You need to press the switch from the right side of the machine to go forward.
You need to press the switch from the left side of the machine to go backwards.
If set in between like this, the drill is locked.
Here it is shown how to use the switch.
Hold the chuck while pressing the on button, to loosen or fasten the drill bit. Set it to reverse to loosen, forward to fasten.
Here I am fastening and loosening without the drill bit, just to show you what it looks like.
I prefer using the magnetic bit holder, so that I can easily replace the bit. The machine also has a better grip on the bit holder than the bit itself.
Most drills have a torque ring like this, that goes from 1 to 20. This is to set the permitted resistance when screwing. 1=highest sensitivity, 20=lowest sensitivity.
There is an additional setting for drilling. When this is set, the clutch will never disengage no matter the resistance. (Bigger drills have yet another setting 🔨 that is used for drilling concrete)
Here the torque is set to 1, 10 then 20. You can see how greater resistance requires lower sensitivity. Because when the permitted resistance is reached, the clutch disengages.
The switch on top sets how to use the energy. Low/1 is stronger and slower. High/2 is faster and weaker.
Here it's set to 2. But as you can see it's not strong enough to loosen the screw.
Here it's first set to 1, to loosen the screw. Then switched to 2, to loosen the screw faster.
