Suited for tougher materials such as alloys, stainless & manganese steels, etc.


  • M35 is not as brittle as M42 & can withstand more torsional stress.
  • M35 is a development of M2 and contains 5% cobalt which provides improved hardness, wear resistance and red hardness.


  • For most general purpose, heavy duty, drilling operations for tougher materials.
  • Well suited for heavy duty operations in high tensile strength, low machinability, ferrous metals and alloys.
  • The 135° split point works for drilling alloy steels, manganese steels, harder stainless steels and a variety of other tough ferrous alloys.
  • Split point design is self-centering and helps to reduce the thrust requirements.
  • Suitable lubricating/cutting oils or appropriate coolant fluids are recommended for most drilling operations to achieve optimal performance & extended tool life.
