Got a Milwaukee M12 polisher or sander and want to use smaller accessories?

This M9 threaded collet adapter is your answer.

It’s specifically designed to fit the M12 series perfectly—threads right onto the M9 interface without any fuss.

Comes with two collets: 1/4-inch and 1/8-inch, so you can swap between larger grinding wheels and fine detail bits depending on the job.

The adapter body is machined from stainless steel, so it resists corrosion and holds up to workshop abuse.

The collets themselves are high-carbon steel, which means they grip your bits tight and don’t loosen up during use—no frustrating wobble or slip.

Installation is a breeze; no special tools required, just thread it on and pop in your accessory.

Great for polishing, sanding, grinding, or even routing small details.

Opens up a ton of new uses for your M12 tool without buying a whole new machine.
