  • Single end mills are general purpose tools designed for general milling operations for slots, grooves and other similar features.
  • The spiral flute design permits a faster and smoother cutting action and the end mills are sized to provide a good cutting range while affording adequate rigidity.
  • For optimal performance and the best tool life the correct cutting speeds and feeds must be used and suitable lubricating/cutting oils or appropriate coolant fluids are recommended.
Non-Center Cutting
  • Used where plunge cutting is not necessary.
  • Peripheral teeth allow for side cutting or contouring an exterior surface.
