Merit Abrasives 69957399766 Quick-change Disc 80 Grit

Product Description

The MERIT ABRASIVES 69957399766 is a coated aluminum oxide quick-change disc designed for aggressive stock removal and weld blending in metal fabrication and finishing applications. This Type 1 (TP) Power-Lock disc measures 1.5 inches in diameter and runs at a maximum of 30,000 RPM. It features a Y-weight 2-ply polyester backing that provides rigidity and durability under sustained load. The aluminum oxide abrasive grain carries a special surface coating that extends disc life and maintains a faster cut rate on moderately demanding grinding tasks. At 80 grit, it falls in the medium-to-coarse range, suitable for initial stock removal and blending passes on metal surfaces.

This disc is engineered for use with handheld disc sanders that accept a Type P (TP, Type I) quick-change attaching system. It performs across a wide range of metals including 300 and 400 Series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. Typical installation scenarios include field grinding, shop weld blending, and surface preparation work where fast, consistent material removal is required. It is sold individually but carries a minimum order quantity of 100 units, making it appropriate for shop stock and fleet supply purchasing.

Installation Notes

Installation is performed by metal fabricators and grinding technicians using handheld disc sanders. Ensure the tool is powered off and disconnected from its power source before changing discs. Verify the tool spindle speed does not exceed the 30,000 RPM disc rating before operation. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or uneven wear.
