Center Cutting
  • Most versatile and allows for plunge cutting or ramping into a cut.
  • Tools have one or more cutting edges at the tip to support plunging.
Non-Center Cutting
  • Used where plunge cutting is not necessary.
  • Peripheral teeth allow for side cutting or contouring an exterior surface.
High Speed Steel
  • High speed steel is consider a good general purpose material for non-ferrous and ferrous materials.
  • Offer good wear resistance and costs less than cobalt or carbide end mills.
  • Offers better wear resistance, higher hot hardness & toughness when compared to high speed steel.
  • Less chipping under severe cutting conditions allows tool to be run 10% faster than high speed steel.


  • Manufactured from high speed steel or M42 cobalt.
