S717 4-flute milling cutters from Dormer are manufactured from premium carbide for superior performance and extended tool life, whilst further improvements in tool life and performance are achieved thanks to the aluminium chrome nitride coating. The high rigidity from the long series flute design is ideal for profile milling deep walls, whilst the 40 degree helix will give high performance profiling on CNC machines. Suitable for plunging, ramping and profile milling in cast iron, steels and stainless steels, S717 milling cutters are highly versatile.
