Merit Abrasives 08834167106 Quick-change Disc 120 Grit

Product Description

The MERIT ABRASIVES 08834167106 is a quick-change abrasive disc designed for use with TR (Type III) and Type R attaching systems on handheld disc sanders. It measures 1-1/2 inches in diameter and carries a 120-grit zirconia alumina abrasive on a rigid polyester cloth backing with a Y-weight rating. The coated blue disc is rated to 30,000 RPM and features an advanced resin bond with a lubricating grinding aid that extends disc life during aggressive stock removal. Fabricators, metalworkers, and finishing technicians use this disc for weld blending, deburring, and surface prep on ferrous and non-ferrous materials.

This disc is suited for work on 300 and 400 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and glass. The 120-grit zirconia alumina abrasive delivers fine-grade cutting action that balances material removal with surface finish quality. It is intended for use with handheld disc sanders accepting Power-Lock Type 3 quick-change connections, making it a practical choice for bench, weld shop, and field metalworking tasks where fast disc changes are required.
