Cylindrical Shank

  • Cylindrical Shank
  • ● Thanks to the small cutting load of the serrated cutting edge and helical interpolation low power consumption. Work smarter and achieve better results.
    ● Serrated cutting edge makes chips small and short, excellent chip control.
    ● Able to cut different materials. ex: Alloy Steel, Stainless steel, cast iron, aluminum, brass, titanium, TiAl6V4, Inconel and hardened.
    ● Each helical mill can machine different diameters and hole depths. Just four helical mills for Ø13~Ø65mm ( Ø0.512 ~ Ø2.559 inch) holes diameter.
    ● Maximum 20° Ramping Angle. Work quicker.
    ● Max. drilling depth 75 mm ( 2.953 inch ).
Holder
