Carbon Brushes Fit Makita Angle Grinders (CB411, 9522NB) – 6x9x12.5mm

If your Makita grinder (like the CB411, CB408, or the classic 9522NB/9520B) is starting to lose power or spark like crazy, it probably just needs new brushes.

These are a set of carbon brushes that are a direct replacement for part number 191940-4.

They measure 6mm x 9mm x 12.5mm, so double-check that fits your model.

They're made to the same specs as the originals, so you can get your tool back to work in no time.

Don't toss that old grinder—pop these in and keep on grinding.
