Dormer 6706650 | 4.00mm Diameter x 6.00mm Shank x 8.00mm Maximum Depth of Cut x 75.00mm OAL x 0.30mm Radius x 40 Degree Helix Angle 4 Flute TiSiN Coated HM S524 Corner Radius End Mill

S524 4-flute milling cutters are manufactured from premium carbide, providing extended tool life and superior performance. They have a long reach flute design with corner radius, giving high rigidity for standard profile milling in hard to reach areas needing a fillet radius, whilst the 40 degree helix gives high performance profiling on CNC machines. S524 milling cutters have a titanium silicon nitride coating for great results when milling difficult to machine materials and further extending the life of the tools. S524 milling cutters are application products-designed particularly for high speed machining in hardened tool steels up to 63HRC.
