The solid hard alloy internally cooled rotary drill bit D16 × L160 × D16 × L220 launched by AMG company is a high-performance drilling tool designed for deep hole machining that requires high depth, high precision, and high efficiency. The drill bit is made of ultra-fine solid hard alloy (HM), which has excellent wear resistance, thermal stability, and fracture resistance.
The optimized spiral groove geometry structure combined with two internal cooling channels significantly improves chip removal efficiency, reduces cutting temperature, and enhances hole position accuracy.
When customers choose hard alloy internal cooling rotary drill bits, they concern selling points are durability, internal cooling effect, machining accuracy, improved efficiency, and long tool life. These features can help customers reduce tool replacement frequency, improve processing quality, reduce downtime, so reducing overall production costs and increasing production capacity.
Applications
This drill is suitable for deep hole machining in materials such as steel, stainless steel, titanium alloys, and alloy steels. It is widely used for aerospace structural components, engine housings, heavy industrial parts, mold cooling channels, —especially where high hole straightness and concentricity are required.

Working Principle
This twist drill features stable spiral flute design that effectively guides chips out of the cutting zone, preventing clogging. The dual internal coolant system delivers high-pressure coolant directly to the cutting edge, improving cooling efficiency and reducing heat-induced wear. The drill’s high-rigidity structure ensures excellent hole precision and straightness even under high-load drilling conditions.
