Description

S535 4-flute milling cutters are intended specifically for high speed machining in hardened tool steels up to 63HRC. The ball nose geometry means they are great for high performance contouring of complex surfaces and the long reach 4-flute design provides good rigidity for increased strength and reduced vibration in difficult to reach areas. S535 ball nose slot drills have a titanium silicon nitride coating which increases service life and improves performance when milling difficult to machine materials whilst the premium carbide used in manufacture further extends tool life and means the tools will provide superior performance.
