Description

The MERIT ABRASIVES 69957399713 is a coated quick-change abrasive disc designed for use with Power-Lock Type R and TR (Type III) attachment systems on handheld disc sanders. The disc measures 2 inches in diameter and is manufactured with aluminum oxide grain bonded to a rigid X-weight, Y-weight 2-ply polyester backing. At 150 grit (Very Fine), it delivers controlled material removal suitable for deburring, cleaning, and surface detailing. Maximum rated speed is 30,000 RPM. The disc is brown in color and belongs to the R766 series. It is sold individually with a minimum order quantity of 100 units.

This disc is intended for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is suited to handheld disc sander applications in fabrication, metalworking, and finishing environments where consistent fine-grit surface prep is required. The aluminum oxide abrasive combined with the polyester backing provides durability and a faster cut rate on ferrous and non-ferrous metals alike. Typical users include metal fabricators, welders, and maintenance technicians performing deburring and surface conditioning work.
