Merit Abrasives 69957399781 Quick-change Disc 150 Grit

Product Description

The MERIT ABRASIVES 69957399781 is a coated aluminum oxide quick-change disc designed for use with Power-Lock Type 1 (TP/Type P) attaching systems on handheld disc sanders. At 2 inches in diameter with a 150-grit very fine grade, this disc delivers controlled material removal for deburring, cleaning, and detailing work on metal surfaces. It is backed by a rigid X-weight 2-ply polyester cloth backing that resists tearing under high-speed operation up to 30,000 RPM. The brown coating over the abrasive layer extends disc life and supports a faster cut rate, making it a reliable choice for repeated use in production or field service environments.

This disc is suited for metalworking applications across a range of ferrous and non-ferrous materials, including 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It performs best in deburring, surface cleaning, and fine detailing tasks where consistent finish quality matters. The quick-change Power-Lock design allows fast disc swaps on compatible handheld disc sanders without additional hardware, reducing downtime during multi-step surface prep. It is commonly used by fabricators, machinists, and maintenance technicians working in shop or field environments. Each package contains one disc, with a minimum order quantity of 100 units.
