Description

The MERIT ABRASIVES 08834166303 is a 2-inch quick-change abrasive disc designed for surface finishing and blending on metal and composite materials. It uses aluminum oxide grain bonded with resin to a flexible non-woven nylon backing, producing a smooth cut rate and a consistent, uniform finish. The disc attaches via a Type R Power-Lock system and is rated to a maximum of 30,000 RPM. Medium grade makes it well suited for general-purpose stock removal and surface prep without aggressive material bite. Licensed tradespeople and fabricators working in production or field environments will find this disc straightforward to swap and run.

This disc is built for use on a range of metal substrates including 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, super alloys, and titanium, as well as fiberglass and composite materials. It is compatible with die grinders, inline grinders, straight grinders, and handheld disc sanders fitted with a Type R quick-change arbor. The non-woven nylon fiber construction resists tearing under lateral load, making it a practical choice for contour work and edge blending where a rigid disc would be less effective.

Installation Notes

Installation is performed by machinists, fabricators, and metalworkers using Type R quick-change arbor tooling. Before mounting, confirm the tool spindle speed does not exceed the 30,000 RPM disc rating. Power down and disconnect the grinder from its power source before changing discs. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or visible wear through the backing.
