Tapered Bristle Disc for Quick-Change Grinders

This tapered bristle disc fits straight grinders, drill presses and pencil grinders that accept a TR quick-change connector. The ceramic bristles are graded at P50 grit for aggressive material removal on metals such as aluminium, brass, bronze, cast iron, stainless steel and steel. Its cup-brush profile reaches contoured surfaces and tight corners where flat discs cannot.

Users needing heavy deburring on hard metals

The coarse P50 grit and stiff ceramic bristles suit weld cleaning, rust removal and edge breaking on ferrous and non-ferrous workpieces. Finishing tasks that require a fine surface preparation or light blending should choose a higher-grit disc instead.

P50 grit ceramic bristles

The single specification that determines suitability is the P50 grit rating combined with ceramic bristle material. This defines the cut rate and surface finish achievable on the listed metals.

Questions about this item

Which tool holders accept the quick-change TR connector on this 18734 bristle disc?

The disc fits straight grinders, drill presses and pencil grinders that have a quick-change TR holder.

Will the ceramic S-type bristles damage softer metals such as aluminium or brass that I still machine?

The disc is rated for aluminium, brass, bronze, cast iron, stainless steel and steel, so it can be used on those softer alloys without gouging when run at recommended speeds.

How can I confirm the disc is cutting correctly once mounted?

A consistent green cutting face and even material removal across the 3-inch diameter show the P50 grit is working as intended.
