Product Description

The MERIT ABRASIVES 69957399792 is a coated quick-change abrasive disc engineered for use with Power-Lock Type 1 (TP/Type I) handheld disc sanders. Measuring 3 inches in diameter and rated at 20,000 RPM maximum, this disc features aluminum oxide abrasive grain bonded to a rigid, X-weight 2-ply polyester backing. The fine-grade, 120-grit construction delivers controlled material removal suited to deburring, surface cleaning, and detail finishing on metal workpieces. Licensed trades and metalworking professionals rely on this disc type for consistent cut rate and extended service life across demanding applications.

This disc is designed for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is compatible with handheld disc sanders using the Power-Lock Type P attaching system. The rigid polyester backing maintains disc geometry under load, making it appropriate for both flat surface work and contour deburring in fabrication, maintenance, and repair environments. The brown coated face provides visual wear reference during use.
