AMG hard alloy internally cooled straight groove drill bit is specially designed for deep hole and blind hole machining .

Product Performance

Wear resistance

Using ultra-fine particle hard alloy (HM) material, it has extremely high hardness and excellent wear resistance, and can maintain stable cutting performance under long-term high load operation.

Hard alloy internally cooled straight groove drill bits have excellent anti chipping performance, which can effectively prevent tool damage under high temperature and high pressure conditions, extend tool service life, and improve the stability of the machining process.

Accurate cooling effect

The internal cooling design sends the coolant directly to the cutting area through a built-in cooling channel, ensuring effective temperature control during the cutting process and avoiding tool wear caused by overheating.

Excellent chip removal ability

The straight groove design is combined with internal cooling system to ensure smooth discharge of chips during the machining process, reducing the impact of chip accumulation on machining accuracy and surface quality.

Adapt to multiple materials

Suitable for various complex machining scenarios such as deep hole machining and blind hole machining

Improve processing efficiency

Internal cooling and good chip removal performance enable the tool to work stably at high cutting speeds and feed rates.

Extend the service life of tools

Through effective cooling and wear-resistant design, the hard alloy internally cooled straight groove drill bit can significantly extend the service life of the tool

High processing accuracy

This drill bit can provide precise hole position and size control, ensuring the depth, diameter, and bottom flatness of the hole meet high standards
