Product Description

The Brilliant Bit® 
Made from a solid brass body and stainless steel set screw, this bit will not corrode over time.
Techniglass uses a proprietary diamond bonding technique to layer diamonds to the metal for a more uniform result. The design improves bit performance by reducing the amount of vibrations transmitted through the glass which produce fatigue cracks. Bit measures 3/4", fine grit produces a smooth surface with virtually no chipping.
