The PAVBDB SERIES is a staple in the Piranha Abrasives product line, covering sizes as small as 1/4” to as large as 5”. Originally introduced as a replacement to a previous coring bit line, these golden painted bits have surmounted the competition, and now stand alone as our most sold coring bit.

• Engineered for Porcelain, Marble
• Dry / Wet Coring
• 5/8"-11 Threaded Adaption
• Variable Speed Grinder
• Vacuum Brazed Segment : Vacuum brazing is a material joining technique that must be performed inside a vacuum chamber vessel. Temperature uniformity is maintained on the work piece when heating in a vacuum, greatly reducing residual stresses due to slow heating and cooling cycles. This, in turn, can significantly improve the thermal and mechanical properties of the material, thus providing unique heat treatment capabilities. All of our PAVBDB SERIES and PAVBDB HEX SERIES Bits combine the process of Vacuum Brazing and the use of Synthetic Diamond to help the coring bits better regulate heat while maintaining a consistent cutting quality
