SHUR-KUT Zirconia Grinding Aid Quick Change Discs from Superior Abrasives reduce heat buildup

Superior Abrasives LLC has introduced SHUR-KUT Zirconia Grinding Aid Quick Change Discs. Their long-lasting, durable grains and sharp cutting action allow for extended stock removal with low heat generation, the company reports. The cooler cut reduces friction and premature breakdown of grains and backing to help lengthen disc life.

A hybrid grain exposes a fresh cutting edge during use for aggressive grinding on stainless steel and exotic alloys, as well as ferrous and nonferrous materials. The discs are suitable for general-purpose grinding and stock removal, deburring or parting line removal on cast parts, spot weld removal and blending, mold and cavity grinding and refurbishing, and grinding and preparing hot castings.

They are available for type S or type R, in 1-1/2-, 2-, and 3-in. dia. for use with right-angle die grinders. Grits are available from 36 to 120, with optimal speeds of 7,000 to 13,000 RPM and maximum speeds from 20,000 to 30,000 RPM.
