4.5-inch 36-grit bristle disc

This 4.5-inch bristle disc uses P36 ceramic bristles for aggressive surface preparation on aluminium, brass, bronze, cast iron, stainless steel and steel. The brown cup brush mounts on a right-angle grinder via a 5/8 in.-11 threaded hole and runs at up to 12,000 RPM. It is built for weld cleaning, deburring and coating removal in metal fabrication shops.

Metal fabricators needing fast stock removal

Technicians cleaning welds, stripping paint or blending edges on the listed metals will benefit from the coarse ceramic grit. Workers finishing wood, plastics or soft non-ferrous alloys should choose a finer abrasive. Anyone whose grinder exceeds the 12,000 RPM limit must select a different disc.

5/8 in.-11 threaded arbor

The disc fits only right-angle grinders with a matching 5/8 in.-11 spindle thread. Verify the tool's arbor size before purchase; an incompatible thread will prevent mounting.

Questions about this item

What arbor size must my right-angle grinder have for this 5/8 in.-11 threaded bristle disc?

The disc fits a 5/8 in.-11 threaded arbor, the standard size on most 4.5 in. right-angle grinders.

Will the 12,000 RPM maximum speed damage a variable-speed grinder set lower?

Running the disc below its 12,000 RPM limit is safe; simply match the grinder speed to the material you are finishing.

How can I confirm the P36 ceramic bristles are cutting correctly after mounting?

A consistent satin finish on steel or aluminum with no gouging shows the 36-grit bristles are working as intended.
