Merit Brass 8834166155 Aluminum Oxide Qc Disc 2in 100 Grit

Product Description

The MERIT BRASS 8834166155 is a 2-inch aluminum oxide quick-change disc designed for surface finishing applications in professional trade and industrial environments. Built on the QC-T3 platform, the disc uses a pressure-sensitive adhesive backing that attaches directly to a compatible disc holder without tools. The abrasive material is aluminum oxide, trade name R422, with a 100-grit rating suited for controlled stock removal and finishing passes. Each package contains 50 discs. The adhesive-backed design includes a protective liner that speeds up disc changes and shields the adhesive surface from airborne work dust between uses.

This disc is intended for finishing operations where consistent surface preparation is required. The QC-T3 format is common in fabrication shops, maintenance facilities, and general metalworking environments. At 2 inches in diameter, it fits standard quick-change disc holders used by machinists, pipefitters, and maintenance technicians for deburring, blending, and light surface conditioning. The 100-grit specification makes it appropriate for intermediate finishing rather than heavy material removal.

Key Features

Installation Notes

Installation is performed by removing the protective liner and pressing the disc firmly onto a clean, dry QC-T3 disc holder surface. Ensure the rotary tool or grinder is powered off and unplugged before mounting or removing discs. Inspect the holder for wear or damage before attaching a new disc, as a compromised holder surface reduces adhesion and can cause disc separation during use. Follow all applicable shop safety protocols and manufacturer guidelines for maximum operating speed.
