Quick Change Discs (Type R - Roloc) used for general purpose grinding and aggressive stock removal. They can also be used for deburring and edge breaking, surface leveling, mold and cavity grinding. Superior's quick change discs are interchangeable/compatible with 3M Roloc, TR and Type III Styles.
- For weld removal use grits 36-60
- To blend gouges, pits and surface imperfections use grits 80-150
- Available in Aluminum Oxide, Silicon Carbide, Ceramic, Zirconia and Zirconia w/Grinding Aid.
- Easy roll-on attachment - Type R (plastic)
- Use on a die grinder
- Cloth backed
- Only sold in box quantity.

Aluminum Oxide: SHUR-KUT™ most popular, durable, general purpose grain. Universally used for metals, wood, plastics, and lacquer. Closed coat, X-Wt. poly/cotton cloth backing - grits 36 - 240
Zirconia: SHUR-KUT™ A synthetic grain engineered to produce tough less brittle characteristics than A/O. Alumina Zirconia Blend. Fracturing properties ensure a consistently sharp edge. Closed coat, X-Wt., cloth backing - grits 36 - 120
Zirconia w/Grinding Aid: SHUR-KUT™ Same properties as standard Zirconia with altered resin chemistry to incorporate a super size coat, which reduces heat and adds lubricity. Aggressive grinding on stainless steel. Closed coat, Y-Wt, polyester cloth backing - grits 36 - 120
Ceramic: SHUR-KUT™ RIGID-KUT™ A synthetic grain formulated to withstand extreme pressures and dissipate heat. Specialized backing for aggressive grinding and high-pressure applications on hard alloys and other metals. Rigid backing and improved grain retention transfer more pressure to properly breakdown ceramic grains, exposing new, sharp cutting edges. Waterproof. Specifically for grinding metal/stainless. Contains a grinding aid. Semi-open coat. Y-Wt., polyester cloth backing - grits 36 - 120 Must apply higher pressure than standard backings.
Silicon Carbide: SHUR-KUT™ Synthetic grain that is very hard and brittle. Designed to grind glass, minerals, ceramic, china, marble, and rock. Waterproof. Closed coat, X/Y-Wt polyester cloth backing - grits - 36 - 400 (please call for finer grits, minimum quantity order applies).
Compact Grain A/O: No longer available online - call, chat or email for pricing and availability. Compact grains are a cluster of multiple abrasive grains of the same size. As one layer of abrasive grain is worn away, another layer is exposed. The compact grain construction results in less loading, much longer life and a very consistent finish. Use compact grains on any mild, stainless or high alloy steel. Grits 80 - 600.
