120 Grit Tapered Bristle Disc

This 3M tapered bristle disc uses ceramic bristles rated at P120 grit for surface conditioning on aluminum, brass, bronze, cast iron, stainless steel and steel. It mounts on straight grinders, drill presses and pencil grinders via a TR quick-change connector for fast tool-free swaps.

Quick-Change TR Mounting

The TR quick-change system locks the disc onto compatible straight grinders, drill presses and pencil grinders without tools. Buyers without a TR-compatible spindle cannot attach this disc. Verify your tool accepts TR connectors before ordering.

P120 Ceramic Grit Rating

The P120 grit rating determines the aggressiveness and finish quality for deburring, blending and cleaning on the listed metals. It is not suited for heavy stock removal or fine polishing tasks that require coarser or finer grits.

Questions about this item

How can I confirm the 3M 18733 disc is running correctly on my straight grinder?

The white ceramic bristles should wear evenly without loading on aluminum or stainless steel, and the quick-change TR connector must stay firmly seated during operation.

What comes with the 18733 tapered bristle disc and what else is needed?

The box contains the 2-inch diameter P120 grit disc with 5/8-inch bristles; a compatible straight grinder, drill press or pencil grinder with a TR quick-change adapter must be supplied separately.

When should I choose the 120 grit version of the 3M 18733 over other grades?

Select the P120 grade for medium blending and finishing on steel, cast iron, brass, bronze, aluminum or stainless steel where a finer surface preparation is required.
