S765 4-flute milling cutters are ideal for roughing when plunging, ramping and profile milling in steels, cast iron and stainless steels.
They have a medium length flute with NR profile, making them ideal for breaking chips, for efficient roughing applications.
The 40 degree helix with unequal flutes means the vibration is reduced and performance improved when used in CNC machines.
S765 4-flute roughing end mills are manufactured from premium carbide, with an aluminium chrome nitride coating.
These two combined will give superior performance and longer tool life when milling materials which are difficult to machine
