Merit Abrasives 69957399774 Quick-change Disc 36 Grit

Product Description

The MERIT ABRASIVES 69957399774 is a 2-inch coated quick-change abrasive disc designed for use with Power-Lock Type 1 (TP/Type I) attachment systems on handheld disc sanders. It uses aluminum oxide grain bonded to a rigid Y-weight 2-ply polyester backing, rated at a maximum of 30,000 RPM. At 36 grit, this disc falls in the extra-coarse range and is built for aggressive stock removal, weld blending, and surface prep on tough base materials. The special grain coating extends disc life and improves cut rate on moderately demanding applications. Metal fabricators and maintenance technicians are the primary users.

This disc is suited for grinding and finishing on 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and titanium. It is part of the R766 series and is intended for handheld disc sander use in industrial, fabrication, and field service environments. The rigid polyester backing maintains consistent contact geometry on flat and near-flat surfaces, making it appropriate for weld bead removal and flush grinding tasks where control matters.

Installation Notes

Installation is performed by metal fabricators or maintenance technicians using a compatible Power-Lock Type 1 mandrel and handheld disc sander. Verify the tool spindle speed does not exceed the 30,000 RPM disc rating before mounting. Inspect the disc for damage before each use and discard any disc that shows cracking, fraying, or separation of the backing. Follow applicable ANSI B7 and OSHA abrasive wheel safety guidelines, including use of appropriate eye and face protection.
