Dormer 6706550 | 12.00mm Diameter x 12.00mm Shank x 16.00mm Maximum Depth of Cut x 125.00mm OAL x 6.00mm Radius x 30 Degree Helix Angle 2 Flute TiSiN Coated HM S533 Ball End Mill

S533 2-flute slot drills from Dormer are just what you need for high speed machining in hardened tool steel up to 63HRC. They have extra long reach in a 2-flute design for good rigidity, increasing strength and reducing vibration in areas difficult to reach, whilst the ball nose geometry makes them great for high performance contouring of complex surfaces. S533 slot drills are manufactured from premium carbide for superior performance and longer tool life, further enhanced by the titanium silicon nitride coating, which also improves performance when milling difficult to machine materials.
