VB Series

6" TO 17 1/2" (152.4 mm TO 444.5 mm) - In Matrix Varel’s VB product line is a premium line of matrix bits featuring two very unique features-oval cutters and lateral hydraulic jet nozzles. The VB series is designed to provide better ROP and longer life than bits designed only with conventional round cutters and hydraulic package. The oval cutter provides more diamond exposure than a round cutter sharing the same diamond width. The sharper tip profile of the oval cutter produces higher point loading, converting applied weight more efficiency than a round cutter, thereby increasing ROP. The lateral jet nozzles, located near the center of the bit, provide greater efficiencies directing flow across the face of the bit for optimal cleaning and cooling of cutters. Lateral nozzles, in combination with conventional nozzles, produce higher ROP and increased bit life.
