Merit Abrasives 08834161318 Quick-change Disc 40 Grit

Product Description

The MERIT ABRASIVES 08834161318 is a 3-inch ceramic coated quick-change abrasive disc designed for high-speed grinding and surface conditioning on metal. It mounts via a Power-Lock Type R attaching system, allowing fast one-handed disc swaps without a wrench. Rated to 20,000 RPM, this disc runs at 40 grit coarse grade, making it well suited for aggressive stock removal, weld blending, and surface prep work. Ceramic abrasive grain delivers consistent cut rates and longer service life compared to aluminum oxide or zirconia on hard materials. The red disc body with black button is a standard visual indicator for this grit and attachment format.

This disc is used in metal fabrication, weld shops, pipe fitting, and general industrial surface prep. It is appropriate for use on angle grinders and die grinders equipped with a Type R quick-change mandrel. Typical applications include deburring, paint and rust removal, and weld seam blending on ferrous and nonferrous metals. Sold individually with a minimum order quantity of 50 units, making it suited for shop stocking rather than single-disc replacement purchases.
