Copper Center Wheels have a small profile for cleaning, polishing and deburring recessed areas such as small openings, slots, machined grooves, fine deburring on medical instruments and gear splines. The CeramiX Copper Center Brushes feature a 3M mineral grain which provides enhanced cutting action up to 3-5 times greater than traditional abrasive filaments. The grain fractures in sharper, jagged surfaces for superior abrasion performance - providing minimum cycle times, increased productivity and maximizes abrasive media on part. The Stem Mount Narrow Face Wheel Brushes are also available in silicon carbide. These brushes are manufactured using nylon embedded with this traditional grit. Silicon carbide is known for its durability, is widely used in many industrial applications and is preferred for finishing ferrous metals.
