Description

The MERIT ABRASIVES 69957399630 is a coated abrasive quick-change disc designed for use with Power-Lock Type 2 (TS/Type II) handheld disc sanders. At 1-1/2 inches in diameter, this disc uses aluminum oxide grain on a rigid, Y-weight, 2-ply cloth and polyester backing. The 80-grit medium grade makes it well suited for deburring, cleaning, and surface detailing on stainless steel, soft metals, and hard carbon steels. It is rated to 30,000 RPM and attaches via a Type S button system, providing a secure, tool-free disc change during production or field work. Metal fabricators, maintenance technicians, and industrial tradespeople are the primary users of this disc.

This disc is built for precision hand-held sanding and grinding applications where a small-diameter, high-speed abrasive is required. The aluminum oxide grain performs consistently on 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and titanium. The rigid cloth and polyester backing maintains disc shape under lateral pressure, which is important when working tight contours, weld beads, or drilled edges. Sold individually with a minimum order quantity of 100 units, this disc is a standard stock item for shops and service teams with ongoing abrasive consumption.
