Alpha® introduces a Wet Core Drill Bit for CNC Machines and Radial Arm workstations. This Core Bit comes with a 1/2” Gas Thread, designed for the tool holder. The diamonds and matrix have been selected to minimize blow-out at the bottom of the stone, since most CNC Router fabrication is done upside-down. This new Core Bit utilizes the superior technology that has made the Alpha® Wet and Dry Core Bits the best in the industry.
