Merit Abrasives 69957399783 Quick-change Disc 240 Grit

Product Description

The MERIT ABRASIVES 69957399783 is a coated quick-change abrasive disc designed for use with Power-Lock Type 1 (TP/Type P) attachment systems on handheld disc sanders. At 2 inches in diameter with a 240 grit aluminum oxide abrasive, this disc falls in the very fine to fine grade range, making it suited for precision deburring, surface cleaning, and detail work on metal substrates. The abrasive layer is bonded to a rigid X-weight 2-ply polyester backing, which provides durability and a faster cut rate compared to lighter-weight backings. Rated to 30,000 RPM, it handles high-speed tool use without delamination risk.

This disc is used in light fabrication, maintenance, and finishing operations on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The Series R766 construction is built for handheld disc sander applications where a small-diameter, fast-change disc is needed for tight areas or detailed work. It is commonly used by metalworkers, fabricators, and maintenance technicians who need consistent surface preparation results without frequent disc changes.
