High Speed Milling Guidelines for Hardened Tool Steels
High speeds for milling of tool steels range from about 1 500 to 3 000 sfm Always consider the actual sharpness of your tool Typical tool edge radius sharpness varies between 0.0002 and 0.0004 therefore realistic chip loads should be a minimum of 0.0010 .
