When should you change the brushes on drills?
As a general rule, if either brush has worn to about a quarter inch long, it is time to replace it. If the carbon (a brush is essentially a carbon block with a metal spring tail) shows any signs of breakage, crumbling, or burning, the brush needs replacing.
Why is my Milwaukee drill smoking?
The carbon brushes supply electricity to the armature by rotating on the commutator. As the carbon brushes wear down, they can spark more. This can cause a heavy carbon build up between the brushes and the commutator, causing the drill to smoke.
Are Milwaukee drills brushless?

Can you replace brushes in a Dewalt drill?
The motor inside your DeWALT cordless drill has two separate carbon brush assemblies: one on each side of the motor. The brushes transfer electricity to the motor’s spinning armature. Because they’re made of carbon, motor brushes will eventually wear down, and will need to be replaced.
Can Milwaukee drill be repaired?
Subject to certain exceptions, MILWAUKEE will repair or replace any part on an electric power tool which, after examination, is determined by MILWAUKEE to be defective in material or workmanship for a period of five (5) years** after the date of purchase unless otherwise noted.
How do I know if my armature needs replacing?
If there’s a banging sound inside the tool’s motor when it runs, then it’s probably a brush. It could also be a bad armature, but if that is the case then it’s most likely that the brushes will have to be replaced anyway. The banging sound is caused by either a damaged or misshapen brush, or a misshapen armature.
Is it normal for a drill to smoke?
As the carbon brushes wear down, they can spark more. This can cause a heavy carbon build up between the brushes and the commutator, causing the drill to smoke. To fix this, you will need to replace the brushes and clean the commutator, which will vary slightly on drills.
Is it normal for Milwaukee drill to spark?
Cordless drills will spark normally within the drill itself as the carbon brushes pass by the commutator. These small sparks are a normal part of the cordless drill operation.
