Screw Fit Type

● Possible apply for enlarge hole and 8xDc deep hole drilling.
● Standard screw-fit body adapts to almost any kind of the screw-fit tool holder or extension bar in the market.
● Designed for CNC machines with internal coolant.
● 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.
