Merit Abrasives 69957399756 Quick-change Disc 120 Grit

Product Description

The MERIT ABRASIVES 69957399756 is a 1-inch aluminum oxide quick-change disc designed for use with Power-Lock Type 1 (TP/Type P) attachment systems on handheld disc sanders. It carries a 120-grit fine abrasive surface bonded to a rigid X-weight 2-ply polyester backing, rated to 40,000 RPM. The coated brown disc delivers a faster cut rate and extended service life compared to standard single-ply backings. It is suited for deburring, cleaning, and detail work on metal surfaces and is typically installed and used by machinists, fabricators, and maintenance technicians working with precision components.

This disc is built for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The small 1-inch diameter makes it well suited for tight access areas, weld seam cleanup, and intricate deburring tasks where larger discs cannot reach. It mounts to handheld disc sanders equipped with a Power-Lock Type P quick-change arbor. The rigid polyester backing maintains disc geometry under load, making it consistent for repetitive production deburring and surface prep operations.
