Merit Abrasives 08834154190 Bore Polisher 60 Grit

Product Description

The MERIT ABRASIVES 08834154190 is a coated aluminum oxide bore polisher designed to clean, deburr, and finish cylindrical bore surfaces in metalworking and machining applications. Rated at 25,000 RPM, it operates at high rotational speeds suitable for use with die grinders and rotary tools. The 60-grit medium-grade abrasive removes material efficiently while leaving a consistent finish inside bores ranging from 5/8 to 1 inch in diameter. This tool is used by machinists, tool-and-die workers, and maintenance technicians who require controlled abrasion inside precision bores.

This bore polisher is suited for use in manufacturing, maintenance, and repair environments where bore surfaces need to be cleaned of rust, scale, burrs, or light surface imperfections. It is appropriate for use on ferrous and non-ferrous metal bores in tooling, cylinder components, housings, and similar workpieces. The coated aluminum oxide construction provides consistent cut rate across the bore contact surface. No interleaf design keeps the abrasive profile straightforward for standard bore polishing tasks.

Installation Notes

Installation and use of this bore polisher should be performed by a qualified machinist or maintenance technician familiar with rotary abrasive tools. Before mounting, confirm the tool RPM rating meets or exceeds the maximum speed of the rotary device being used. Always secure the workpiece and wear appropriate personal protective equipment including eye protection before operating. Do not exceed the rated 25,000 RPM maximum.
