How do you put a drill brush on a drill?

To attach a drill brush to a drill, you insert the brush's bit into the drill's chuck, then tighten the chuck collar to secure the brush.

Here's a more detailed breakdown:

1. Open the Chuck: Loosen the collar of the drill's chuck (the part that holds drill bits) by turning it counter-clockwise. This opens the jaws of the chuck.

2. Insert the Brush Bit: Insert the shank or bit of the drill brush into the opened chuck. Make sure it is centered.

3. Tighten the Chuck: Rotate the chuck collar clockwise to tighten it. Most drills have a ratcheting chuck, so you'll hear clicks as you tighten. Tighten firmly, but don't overtighten. The goal is to hold the brush securely without damaging the chuck or the brush bit.

4. Test the Connection: Briefly run the drill at a low speed to ensure the brush is securely attached and doesn't wobble excessively. If it does, stop and re-tighten the chuck.

Removing the brush is just as simple:

1. Loosen the Chuck: Rotate the chuck collar counter-clockwise to loosen the jaws.

2. Remove the Brush: Pull the brush straight out of the chuck. You might need to wiggle it slightly if it's stuck.
