How to Change Dremel Brushes

Overview

Dremel makes handheld power rotary tools for woodworking, drilling, grinding and brushing. Changing Dremel brushes takes only a moment when you follow the correct procedure for removing one bit to replace with another. The process seems lengthy, but is not complicated. Safety features are built into Dremel tools preventing them from operating unless the bits are installed correctly.

Step 1

Press and hold the metal lock button near the tip of the tool.

Step 2

Remove the collet nut by turning counterclockwise, then release the lock button.

Step 3

Remove the housing nut on the end of the tool by turning counterclockwise. The housing nut is about the size of a nickel with a hole in the center. Leave the housing nut loosely on the thread at the end of the tool

Step 4

Pull the collet, which is a metal tube wider at the tip, from the front of the collet nut.

Step 5

Select a Dremel brush bit to use in the tool and choose a collet to fit the brush. Dremel tools come with four collet sizes to use with different bits, including the brushes. The bit must fit firmly in the collet without forcing.

Step 6

Slide the collet into the front of the collet nut.

Step 7

Slide the collet and collet nut assembly over the threaded drive shaft of the Dremel tool. The collet slips inside the drive shaft until it is seated and the collet nut threads over the drive shaft.

Step 8

Tighten the collet nut while pressing the lock button until you hear the collet click.

Step 9

Tighten the housing nut. The Dremel tool with a new brush is ready to use.
