Merit Abrasives 08834166397 Quick-change Disc 3 in Coarse

Product Description

The MERIT ABRASIVES 08834166397 is a 3-inch quick-change abrasive disc designed for surface preparation, blending, and finishing on metal and composite materials. It uses aluminum oxide grain bonded with resin to deliver a smooth cut rate and a consistent surface finish. The non-woven nylon fiber construction is laminated to a tough backing that resists tearing under load. Rated to 20,000 RPM, this coarse-grade disc attaches via a Type S Power-Lock system, making tool-free disc changes fast and secure on compatible rotary tools. It is suited for metal fabrication shops, maintenance technicians, and trade professionals who need reliable performance on demanding materials.

This disc is built for use on a range of materials including 300 and 400 Series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass or composite substrates. It is compatible with die grinders, handheld disc sanders, inline grinders, and straight grinders. Typical applications include weld blending, surface conditioning, deburring, and light stock removal in fabrication and field service environments.
