  • ISO P materials, the first choice for semi-finishing of various steel.


Technical Information:

  • Steel is the largest material group in metal cutting.
  • The machinability of steel varies depending on its alloying elements, heat treatment and manufacturing processes (forging, casting, etc.).
  • Generally, steel has good machinability, but the specific properties vary greatly depending on the hardness of the material and the carbon content.
  • For turning, steel can be divided into non-alloy steel, low alloy steel and high alloy steel.
    • Non-alloy steel:
      • Material classification: P1.1
      • Non-alloy steels include steels with a carbon content of 0.55% or less.
      • For low carbon steel (<0.25%), due to the difficulty of chip breaking and the tendency of bonding, special care should be taken during processing.
      • For non-alloy steels with higher carbon content, the processing characteristics are similar to those of low alloy steels.
    • Low-alloy steel:
      • Material classification: P2.x
      • Low alloy steel is the most commonly used material in metal cutting. Such materials include both soft and hard materials (below HRc 50).
      • For low hardness materials, the most common types of wear are crater wear and flank wear.
      • The machinability of low alloy steel depends on the alloy content and heat treatment (hardness).
      • Hard deformation of hard materials is a common type of wear, which generates more heat in the cutting area.
      • Hard material cutting tools require extremely high heat and flank wear resistance, so for these processes, cast iron machining grades can be used.
    • High alloy steel:
      • Material classification: P3.x
      • High alloy steels include carbon steel with a total alloy content of more than 5%.
      • High alloy steel includes both soft and hard materials (below HRc 50).
      • Cutting performance decreases as the alloy content and hardness increase.


Feature Advantage:

  • With special sintering technology, the impact resistance and wear resistance of the cutting edge are enhanced to improve the resistance of the cutting edge.
  • The blade adopts special surface technology, which greatly improves the surface quality of the blade, effectively reduces the cutting force, reduces the bonding between the blade surface and the material to be processed, and greatly improves the stability of the blade.
  • The unique cutting edge skeleton design achieves the perfect combination of blade toughness and resistance to plastic deformation.


  • Chipbreaker, PM:
    • Very versatile chipbreaker, wide cutting depth, can also be applied to the processing of a variety of materials.
    • M-class precision chipbreaker type.
    • High edge strength.
    • Lower cutting force.
    • Suitable for semi-finishing with unstable working conditions and for cast iron machining.


  • Grades:​​

Recommended Cutting Parameters:

  • The following cutting parameters are the recommended range values. Appropriate adjustments and selections should be considered after considering the following factors:
    • Specific physical properties of the material being processed
    • The actual condition of the part blank
    • Power and rigidity of the machine tool
    • Clamping rigidity of tools and workpieces
    • Balance between tool life and machining efficiency
