Feature and advantages:
·The tool body is made of high-quality tool steel that has undergone special heat treatment, with the entire surface treated by coating, which is wear-resistant and rust-proof.
·HB type side-fixed tool holder and sturdy flanged tool body to reduce vibration or jitter
·Three types of channel-shaped solid carbide drill tips are suitable for processing materials such as carbon steel, cast iron, stainless steel, high-temperature alloys, and aluminum alloys.
·The drill tip adopts a side-fixing locking screw, making it more convenient to replace the drill tip.
·The diameter range is ⌀8-39.99mm(0.315 - 1.57 in), and the processing depth is 3D, 5D, 7D, 10D and 12D. Other specifications can be customized non-standard.
·The internal cooling with threaded interface design facilitates the connection of high-pressure coolant externally and ensures smooth chip removal.
