Product Description

The MERIT ABRASIVES 69957399682 is a coated quick-change abrasive disc designed for use with Power-Lock Type 3 (TR/Type III) handheld disc sanders. At 1 inch in diameter with a 36-grit aluminum oxide abrasive, this disc falls in the extra coarse grade range, making it well suited for aggressive material removal, deburring, and surface preparation. The disc features a two-ply cloth and polyester backing rated at Y-weight, which provides a rigid, durable platform during high-speed grinding. It is rated to a maximum of 40,000 RPM and attaches via a Type R attaching system.

This disc is used in handheld disc sander applications across fabrication, maintenance, and finishing environments. It is appropriate for both residential shop and commercial or industrial settings where fast stock removal or cleaning of metal surfaces is required. The extra coarse 36-grit construction handles demanding applications on a wide range of metals including 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, and titanium. It is particularly effective for deburring, cleaning, and detailing stainless steel and soft metals.
