BHA Green Zirconia Quick Change Discs – 3-Inch (36 Grit) Type R Roll-On, 25 Pack

Overview

Meet the 3 in Zirconia Plus Quick Change Discs from BHA designed for metal stock removal, blending, deburring, finishing, and polishing on flat or contoured surfaces. The compact 3 inch diameter helps reach tight spaces and enables detailed work where larger discs can struggle.

Premium closed coat zirconia grains fracture during use to continually expose sharp points, delivering a faster cut rate than standard aluminum oxide options. The resin over resin bond offers moisture resistance and improved grain retention under heat, helping these discs hold up under demanding tasks.

Active Grinding Aid helps prevent loading and reduces heat buildup, which can protect the workpiece from staining or burning and helps keep the disc sharper longer. The discs fit on 3 inch backing pads and attach to 1/4 inch shank tools via a Type R male roll on roll off system, making quick swaps on compatible drills and grinders straightforward.
