Dremel motor

[Jay]

I've been working my Dremel quite hard and I'm suspicious that the motor might be on its way out. When it's running at the highest rpm setting there are slight hesitations which weren't there before I was working the tool hard. Could this be something more than worn brushes? Any thoughts?

it is the replaceable motor brushes. they need to be replaced

also check the springs holding the motor brushes.
they need to be lined up properly to hold the brushes down.

Mine started doing this right before the motor ate itself for breakfast.
