Features and Benefits
Type R attachment systems feature roll-on/roll-off style fasteners (External Thread). They are interchangeable with Roloc, TR and Type III Styles.
More durable than aluminum oxide, zirconia-alumina is best for medium- to heavy-material removal. The material grains constantly fracture to produce new sharp edges. Commonly used on carbon steels, aerospace alloys, nickel alloys, aluminum, cast iron, forgings and some stainless steels.
