BHA Green Zirconia Quick Change Discs with Grinding Aid – 2-in Type R Roll-On, 60 Grit, 25 Pack

Overview

The BHA Green Zirconia Quick Change Discs with Active Grinding Aid deliver a balanced mix of efficiency and control for metalworking. Sized at 2 inches, they excel in stock removal, blending, deburring, leveling, grinding, and finishing on flat or contoured surfaces. Their compact diameter makes them especially useful in tight spaces and for detail work where larger tools can struggle to reach.

Why zirconia with grinding aid

• Premium closed-coat zirconia grains fracture to continuously reveal sharp points for a faster cut compared to basic oxide options.
• Moisture-resistant, heat-resistant resin bonding helps retain grain integrity and extend useful life in demanding tasks.
• Active Grinding Aid minimizes loading and reduces heat buildup, helping protect workpieces from staining or scorching while keeping the disc sharper longer.
• Heavy-duty Y-weight polyester backing and a Type R quick-roll-on/roll-off system enable quick changes on compatible backing pads.

Real-world uses and outcomes

In automotive, fabrication, and metalworking environments, these discs help teams remove material efficiently on carbon steel, cast iron, titanium, and aluminum. They also support finishing and deburring on copper, brass, and other alloys, with a reduced risk of overheating in sensitive areas. The small diameter supports precision in crevices, joints, and contours, while the grinding aid helps maintain a steady cutting action across passes. Results will vary by material and technique, but users often experience cleaner edges and fewer reworks compared with larger, less advanced discs.

Material compatibility and care tips

These discs perform well on carbon steel, cast iron, titanium, aluminum, brass, bronze, and copper, and can handle heat-sensitive materials such as stainless steel, nickel alloys, and cobalt alloys when used with proper technique. For best results, pair with a suitable 2-inch backing pad and a 1/4-inch shank tool. Avoid applying excessive pressure, and inspect discs for glazing or wear to maintain peak performance over time.

Quality and durability

The zirconia grains, combined with the grinding aid and resin bond, offer a robust, long-lasting cutting edge. The backing and fixing system are designed for repeated disc changes in fast-paced shop environments, helping keep workflow efficient without sacrificing finish quality.
