Application & materials

The tapered bristle disc removes burrs, oxides and surface contamination from aluminium, brass, bronze, cast iron, stainless steel and steel. Ceramic bristles in a P50 grit deliver aggressive cutting while the tapered profile reaches inside corners and contoured areas. The green colour identifies the abrasive grade at a glance. It mounts on straight grinders, drill presses and pencil grinders via a quick-change TR connector.

Who should choose this

Metalworkers who need a single disc for deburring and cleaning multiple ferrous and non-ferrous alloys will benefit from the broad material compatibility. Shops that prefer slower material removal or require a mirror finish should select a finer-grit or non-woven alternative instead.

Grit grade

The P50 ceramic grit determines stock-removal speed and surface profile; verify that this coarseness matches the finish specification for the workpiece before fitting the disc.

Questions about this item

How does the P50 grit perform when the disc is mounted on a straight grinder?

The P50 ceramic bristles give aggressive stock removal on aluminum, brass, bronze, cast iron, stainless steel and steel while the tapered shape reaches contoured areas without loading.

What does the TR quick‑change system require on the tool side?

A matching TR quick‑change holder on the straight grinder, drill press or pencil grinder lets the 2‑inch disc snap in and out without tools.

What shank or arbor does the 2‑inch tapered disc need to fit?

The disc uses the TR quick‑change connector, so it mounts directly onto any compatible TR holder — no separate arbor or shank is required.
