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.
