Merit Abrasives 69957399685 Quick-change Disc 60 Grit

Product Description

The MERIT ABRASIVES 69957399685 is a coated quick-change abrasive disc designed for use with Power-Lock Type 3 (TR/Type III) and Type R attachment systems. It measures 1 inch in diameter and carries a 60-grit aluminum oxide abrasive on a rigid, X-weight, 2-ply cloth and polyester backing. The brown disc is rated to a maximum of 40,000 RPM. This configuration is suited to deburring, cleaning, and surface detailing tasks on stainless steel, soft metals, and hard carbon steels. It is installed and operated by metalworkers, fabricators, and maintenance technicians using handheld disc sanders.

This disc is used in light-duty grinding and surface preparation applications across a range of metals including 300 series and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and titanium. The small 1-inch diameter makes it well suited to detail work, tight clearances, and weld seam cleanup where a larger disc cannot reach. It is intended for handheld disc sander use in both shop and field environments.
