End MillCharacteristics and Features
- High red hardness for high heat conditions
- Multi-flute end mills deliver a smoother finish and are better for peripheral cuts
- Multi-flute end mills have a heavy duty cross section for better rigidity
- Increased number of flutes mean more cutting edges, providing more cutting action
- Coatings reduce heat and abrasion to increase tool life
- The increased lubricity of the coating surface reduces material adhesion and built-up edge, enabling even higher feed rates
- Coatings reduce the amount of torque required for machining to allow more efficient use of equipment
- Applicable on titanium alloys, nickel alloys, cobalt alloys and stainless stee
