3M Resin Bond Hot Pressed Wheel 53HB is a conventional grinding wheel featuring zirconia grains. This wheel is designed for slab grinding operations on carbon, alloyed and titanium materials. About Resin Bonds 3M Resin Bond Hot Pressed Wheel 53HB is a hot pressed wheel with a resin bond. Synthetic resin bonds consist of phenolic resins and various fillers that have a decisive influence on the bonding properties. Wheels with these bonds are less sensitive to sudden temperature changes, shock and impact than wheels with a vitrified bond. This particular grinding wheel is targeted for slab grinding operations on carbon, alloyed and titanium materials, and features zirconia grains as the concentrated grinding element.
