Merit Abrasives 69957399764 Quick-change Disc 50 Grit

Product Description

The MERIT ABRASIVES 69957399764 is a Power-Lock Type 1 quick-change abrasive disc designed for use with handheld disc sanders in metal fabrication and finishing applications. The disc measures 1-1/2 inches in diameter and carries a 50-grit coarse aluminum oxide abrasive surface. It features a 2-ply Y-weight polyester backing rated for rigidity and durability under demanding grinding conditions. A special grain coating promotes faster cut rates and longer service life. Maximum operating speed is 30,000 RPM. This disc is installed and used by metal fabricators, welders, and maintenance mechanics performing stock removal and weld blending tasks.

This disc is suited for moderately demanding metal finishing work, including stock removal and weld blending on a range of ferrous and non-ferrous materials. Compatible materials include 300 Series Stainless, 400 Series Stainless, Aluminum, Brass, Bronze, Hard Carbon Steels, Soft Carbon Steels, and Titanium. It is intended for use with a handheld disc sander equipped with a Power-Lock Type P attachment system. The coarse 50-grit grade makes it appropriate for aggressive material removal rather than fine finishing passes.
