 GRAINS FOR BONDED ABRASIVES
Essential to Performance and Durability
Using high quality abrasive grains with uniform characteristics which are consistent in size, shape, color, chemistry and toughness These grain elements provide optimal bonding capabilities, and predictable grinding ratios which leads to longer wheel life
Aluminum Oxide
Friable
White - High purity
Pink | Semi-friable Specialty treated
High density
Tough medium density brown
Zirconia
High performance fused alumina zirconia grain
Outlasts standard aluminum oxide 3 to 1 Hard, tough, sharp
Ceramic
Seeded gel product | Most durable grains available Unique nano structure allows uniformed fracture
when stressed
Ceramic grains are known to out perform zirconia
Silicon Carbide
High purity green silicon carbide when friable is required Grain helps eliminate clogging when cutting off soft materials
Black silicon carbide
