Merit Abrasives 69957399742 Quick-change Disc 80 Grit

Product Description

The MERIT ABRASIVES 69957399742 is a quick-change coated abrasive disc designed for use with Power-Lock Type 1 attachment systems on handheld disc sanders. Measuring 3/4 inches in diameter, this disc features 80-grit aluminum oxide abrasive grain on a rigid Y-weight 2-ply polyester backing. The special grain coating extends disc life and maintains a faster cut rate compared to standard coated discs. This disc is built for moderately demanding stock removal and weld blending tasks and is sold individually with a minimum order quantity of 100 units. Tradespeople in metal fabrication, welding, and general industrial maintenance are the primary users.

This disc is suited for use on a range of metals including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The 80-grit medium-to-coarse cut makes it effective for weld blending, surface prep, and stock removal in fabrication shops and field service environments. It mounts to handheld disc sanders using a Power-Lock Type P attachment system, which allows fast disc changes without additional tools. The brown polyester-backed disc handles elevated heat and lateral stress well in rigid grinding applications.
