Merit Abrasives 69957399670 Quick-change Disc 36 Grit

Product Description

The MERIT ABRASIVES 69957399670 is a quick-change abrasive disc designed for use with Power-Lock Type R attachment systems. Measuring 3/4 inch in diameter, this disc features 36-grit aluminum oxide abrasive on a rigid polyester backing, rated for a maximum of 40,000 RPM. The coated aluminum oxide construction delivers aggressive stock removal on metal, weld seams, and surface preparation tasks. The brown disc color and black button are characteristic of the R766 series. At 0.01 pounds, this is a single-piece consumable intended for high-volume use in fabrication, maintenance, and finishing operations.

This disc is suited for metalworking applications where rapid disc changes and consistent cut rate are required. The Type R quick-change attachment system allows tool-free swaps on compatible grinders and die tools, making it practical for production environments, MRO shops, and field repair work. The very coarse 36-grit rating makes it appropriate for aggressive grinding, weld blending, and deburring on steel and other ferrous metals. Minimum order quantity is 300 pieces, making this a shop-supply or stocking purchase rather than a single-unit replacement.

Installation Notes

Installation is performed by a machinist, fabricator, or maintenance technician using a compatible Type R mandrel. Always confirm the tool spindle speed does not exceed the disc maximum RPM rating of 40,000 before operation. Power down and disconnect the tool from its power source before mounting or removing the disc. Inspect the disc for damage before each use and do not use damaged or delaminated discs.
