Merit Abrasives 69957399770 Quick-change Disc 180 Grit

Product Description

The MERIT ABRASIVES 69957399770 is a coated quick-change abrasive disc designed for use with Power-Lock Type 1 (TP/Type I) handheld disc sanders. Measuring 1-1/2 inches in diameter, it features 180-grit aluminum oxide abrasive on a rigid X-weight 2-ply polyester backing. That combination of durable grain and stiff backing delivers a faster cut rate and extended disc life compared to lighter-backed alternatives. The disc is rated to 30,000 RPM. It is suited for deburring, surface cleaning, and detailing work on metal substrates. Metalworkers, fabricators, and maintenance technicians are the primary users of this disc in production and repair applications.

This disc is intended for use in handheld disc sander applications where a quick-change Power-Lock Type P attaching system is present. It performs on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The rigid polyester backing and fine aluminum oxide grain make it well suited for finish work and surface prep on tight or detailed workpieces where controlled material removal is required. It is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop-stock and production environments.

Installation Notes

Installation requires a compatible Power-Lock Type P quick-change disc sander; no tools are needed to mount or remove the disc. Before mounting, confirm the tool spindle speed does not exceed the 30,000 RPM disc rating. Always wear appropriate eye and hand protection when operating abrasive discs at speed. Inspect the disc for damage or delamination before each use and discard any disc that shows signs of wear beyond the abrasive layer.
