Hardness

Almost no restriction

Almost no restriction

Problems with very soft, hard or brittle materials Hardness can be a consideration

Hardness must be consulted

Typical
180 - 600 HV

Stress

No stress

Thermal stress on the cutting edges

Stress at the cutting edge or close to it

Deformation, tempering and structural changes may occur in the material

Limited stress on the cutting edge Low stress
