Dormer 6707005 | 20.00mm Diameter x 20.00mm Shank x 38.00mm Maximum Depth of Cut x 104.00mm OAL x 40 Degree Helix Angle 4 Flute AlCrN Coated HMS761 Square End Mill

S761 4-flute milling cutters have a 40 degree helix with unequal flute divide which reduces vibration and improves surface finish when milling using CNC machines, whilst the medium length flute gives high rigidity for standard profile milling. The tools have an aluminium chrome nitride coating which improves performance when milling hard to machine materials and prolongs tool life, whilst the premium carbide used in manufacture further extends tool life and ensures superior performance. S761 4-flute milling cutters can be used for plunging, ramping and profile milling in cast iron, steels and stainless steels, making them a very versatile choice.
