Superior Abrasives A019076 Aluminum Oxide Bore Polisher 60 Grit

Product Description

The SUPERIOR ABRASIVES A019076 is a coated aluminum oxide bore polisher designed for internal bore finishing in a wide range of materials. Rated at a maximum of 22,000 RPM and carrying a medium grade, 60-grit abrasive surface, this tool handles bores ranging from 3/4 to 1 inch in diameter. The 1/4-inch shank length makes it compatible with flex shaft tools and straight shaft die grinders. It is used by machinists, toolroom technicians, and maintenance professionals who require consistent, repeatable surface finishing inside bored holes and cylindrical cavities.

This bore polisher is suited for use on composite materials, exotic alloys, ferrous metals, non-ferrous metals, plastics, and stainless steel. It fits into production and maintenance workflows where ID finishing, light stock removal, or surface conditioning inside a bore is required. The SK-3 series designation identifies it within SUPERIOR ABRASIVES' coated bore polishing line. It mounts directly into a flex shaft tool or a straight shaft die grinder for handheld or bench-mounted operation.

Installation Notes

Installation is performed by machinists or maintenance technicians using a straight shaft die grinder or flex shaft tool. Ensure the workpiece is fully secured and the tool is powered off before mounting the bore polisher into the collet. Do not exceed the 22,000 RPM maximum speed rating. Inspect the abrasive for wear or damage before each use and replace if the coated surface is compromised.
