Serrated Design: diamond hole saw has saw-shaped teeth on the top to ensure sharp teeth and fast drilling speed. The openings between the sawteeth are neat, and there are multiple chip removal grooves, which can quickly discharge dust during the drilling process and is not easy to block, thus improving the work efficiency The core bit is designed for Drilling a hole to porcelain tiles, ceramics, marble, granite, stome,etc Diameter 25mm(1"), triangle shank connection, diamond height 10mm, total length 65mm, diamond grit 40/45; the recommend speed is 2000rpm, the max speed is 5000rpm Advanced technology: All brazed hole saws are treated by a special high-temperature resistant process. they can withstand the huge heat generated by the hole saw when it rotates at high speed. Water can be an additional coolant to extend the service life Vacuum brazed technology provides excellent drilling strength for high-precision and smooth cutting, and the drilling is stable and fast ABOUT PRODUCTION:
