1. Significantly extend the service life of cutting tools (most crucial)

The hardness and wear resistance have increased; the service life of high-speed steel tools has generally increased by 30% - 80%, and in some cases, it can double, reducing the frequency of tool replacement.

2. Stabilize dimensions and reduce deformation

3. Enhance hardness and red hardness

After deep cooling, the overall hardness of high-speed steel increases by 1-3 HRC; during high-temperature cutting, the anti-softening ability (red hardness) becomes stronger, and the high-temperature cutting edge is less likely to become softened due to annealing, making it suitable for high-speed cutting and dry cutting.

4. Improve toughness and reduce chip breakage

5. Reduce friction coefficient and slow down blade sticking
