Merit Abrasives 69957399645 Quick-change Disc 150 Grit 2 in

Product Description

The MERIT ABRASIVES 69957399645 is a 2-inch quick-change coated abrasive disc designed for use with Power-Lock Type 2 (TS/Type II) attachment systems. It features 150-grit aluminum oxide on a rigid X-weight 2-ply polyester backing, delivering a fast cut rate and extended service life compared to lighter backing grades. Rated to 30,000 RPM, this disc is built for handheld disc sanders used in deburring, surface cleaning, and detail finishing on metal workpieces. The coated abrasive construction distributes cutting action evenly, making it a reliable choice for repetitive material removal tasks in fabrication and maintenance applications.

This disc is suited for work on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It fits handheld disc sanders equipped with a Type S or TS (Type II) quick-change interface. The 2-inch diameter makes it practical for tight access areas, weld seams, and detail work where a larger disc cannot maneuver. The very fine 150-grit grade is appropriate for finishing passes and light deburring rather than aggressive stock removal. Typical users include metal fabricators, pipefitters, welders, and maintenance mechanics.
