The Dust Muzzle Ultra is the first completely universal dust collector for grinders. It fits all round head and square head electric and pneumatic grinders. For smaller bearing housings, the flexible adapter ring is used. For larger diameter bearing housings the flexible adapter ring is necessary.
By using the spacer washers, the Dust Muzzle Ultra can accommodate all diamond cup wheels, soft pads, polishing pads and abrasive wheels.
