BHA Green Zirconia with Grind Aid Quick Change Sanding Discs Type R Male Roll On, 2" (36 Grit) - 25 Pack

2-Inch Zirconia Quick Change Discs with Grinding Aid

The BHA Green Zirconia Quick Change Discs with Active Grinding Aid are designed for metal stock removal, blending, deburring, leveling, grinding, finishing, and polishing on flat or contoured surfaces. The small 2-inch diameter shines in tight corners, edges, and restricted spaces where larger tools struggle, making detail work more efficient and less intrusive.

Fresh, sharp performance comes from premium closed-coat zirconia grains that fracture during use, continually exposing a fresh cutting point for a faster cut rate compared to standard aluminum oxide discs. The zirconia grains are resin over resin bonded, delivering moisture resistance, heat tolerance, and strong grain retention. The integrated active grinding aid helps prevent loading and reduces heat buildup, helping protect the workpiece finish and keeping the edge crisper for longer draws of use.
