In more advanced drills such as DCD996 or Milwaukee Fuel 18, clutch is also connected to a controller which shuts the motor down when disengaged and is only reset when trigger switch is released.

So the motor will continue to rotate no matter what. Under no load, the sun (central gear) will rotate the planet gears which will rotate the carrier and the chuck. When the chuck is blocked, the planet gear will turn the outer ring (green) instead. The spring applies a force to the small round bearings and notches on the outer ring. When you select the torque you compress more or less the spring and increase or decrease the force it applies on the outer ring notches to keep it blocked. So, for the planet gears to keep turning it's a matter of choosing the less resistance path. If the chuck encounters resistance and the spring is compressed, the outer ring is kept in place with a greater force so the planet gears will turn the chuck. If the spring has little compression, it will be easier for the planet gears to turn the outer ring instead since it encounters less resistance than turning the chuck.

We evolve, beyond the person that we were a minute before.
Little by little, we advance with each turn.
*That's how a drill works!*

Sorry but I think that I need a little more information about this. 👍👍👍

I think making the teeth on the collar that contact the bearings more visible will help those very new to mechanical stuff; everything else mostly explains itself.

Great video!
I like the part where the drill drills.

Hello. I'm wanting to leave the minimum torque as weak as possible. If I cut the spring, will the minimum torque be weaker? And if I take the spring out, what happens? Does the chuck not turn without the spring pressing? Thanks.

THIS IS THE DRILL THAT WILL PIERCE THE HEAVENS 🥽

It is very important not to screw the clutch too tight, the engine will burn.

I took mine apart and lost the balls lol now the ring gear is epoxied in

This is only helpful if you already know how the mechanism works. Completely useless to explain how it works.
