You can do that, however the brush will wear faster as well as the comm. If you are changing brush, best thing to do is get the comm cut too.

You can also get more life out of your brushes if you cut the comm really often. But if you don't mind doing both, I would do both, because I do.

Thumbs down !!!!!!

as the motor runs and the brush makes contact with the com It archs leaving the com with this shape lvl grove . If you put on new brushes it Will cause a glitch. thats why you must true the com when you change brushes........... always
