Merit Abrasives 08834167117 Quick-change Disc 60 Grit 3 in

Product Description

The MERIT ABRASIVES 08834167117 is a 3-inch quick-change abrasive disc designed for aggressive material removal on metal, wood, and composite surfaces. Built on a heavy Y-weight polyester backing, this coated disc uses a zirconia alumina abrasive grain at 60 grit for fast stock removal with consistent cut rate. It attaches via a Power-Lock Type R system and is rated to 20,000 RPM for use with handheld disc sanders. The flexible construction allows the disc to conform to contoured surfaces, and the self-lubricating treatment helps reduce heat buildup during extended grinding. Licensed trade fabricators, welders, and metalworkers are the primary installers of this consumable.

This disc is suited for stock removal, weld blending, and deburring applications across a wide range of materials. Rated material applications include 300 Series Stainless, 400 Series Stainless, Aluminum, Brass, Bronze, Fiberglass and Composites, Hard Carbon Steels, Soft Carbon Steels, Hard Woods, and Soft Woods. It is compatible with handheld disc sanders accepting TR (Type III) or Type R quick-change attachments. The 3-inch diameter and flexible Y-weight backing make it well suited for tight weld joints and curved workpiece profiles.
