Dormer 7648854 | 12.70mm Diameter x 12.70mm Shank x 1" Maximum Depth of Cut x 76.20mm OAL x 30 Degree Helix Angle 4 Flute Bright Coated HM S138 Ball End Mill

S138 4-flute end mills have ball nose geometry for high performance contouring of complex surfaces. They can be used for plunging, ramping and profile milling in steels, stainless steels and cast iron and are manufactured from premium carbide for improved performance and longer tool. The bright finish ensures a clean and accurate result by preventing workpiece material from sticking to the cutting edges of the tool, whilst the medium length flute makes sure you have the rigidity needed for increased strength and reduced vibration.
