At present, the commonly used planer materials are high speed steel and cemented carbide.

The cutting part of the planer works under high temperature and severe friction, so the tool material must have the following properties:

1, the hardness of high hardness (cold hardness) tool material is higher than that of the processed material.

2. High wear resistance makes the tool not easy to wear in the long-term cutting process.

3. High heat resistance means that the tool can still maintain good cutting performance at high temperature.
