3M 7010368436 Ao Slotted Cloth Disc 3 Inch 80 Grit

Product Description

The 3M 7010368436 is an aluminum oxide slotted cloth disc designed for use with a compatible mandrel in push applications on internal surfaces. The slotted construction allows the disc to compress when inserted into a hole, bore, or cylinder, maintaining full contact with the internal diameter throughout the stroke. At 3 inches in diameter and 80 grit, it provides moderate stock removal suitable for light deburring, blending, cleaning, polishing, and chamfering. The cloth backing resists tearing and fraying under load, extending service life. A threaded eyelet arbor hole accepts a compatible mandrel. This disc is installed and used by machinists, fabricators, and trade professionals working on precision internal surfaces.

This disc is suited for push-style internal grinding and finishing work on steel, rubber, plastic, and composites. Typical applications include deburring drilled holes and bores, blending internal welds, cleaning cylinder walls, and chamfering internal edges. The 3-inch diameter is intended for use in workpiece openings with an internal diameter at least 0.5 inches larger than the disc. It is appropriate for both light production and maintenance work in shop or field environments where internal surface finishing is required.

Compatibility

Designed for use with compatible Standard Abrasives mandrels, sold separately. Select a disc diameter at least 0.5 inches smaller than the internal diameter of the workpiece for proper fitment and full contact.

Installation Notes

Install the disc onto a compatible threaded mandrel before mounting the mandrel in a rotary tool or drill. Do not exceed the rated 8,000 RPM maximum speed. Power down and de-energize the tool before attaching or removing the disc. Inspect the disc for damage before each use and replace if slotting, cloth backing, or abrasive surface shows signs of wear or tearing.
