Failure to observe the precautions may cause serious damage to human body. Revolution Balance quality grade G (min-1) ISO1940-1/8821 Warning about Max. Revolution indicated on main body (JIS B0905) 1. When running the end mill and the face mill at revolutions exceeding the maximum revolution limit, the inserts or toolholder may be damaged due ~20,000 G16 to the centrifugal force. ~30,000 G6.3 2. For actual practical revolution, please set within recommended cutting condition. 30,000~ G2.5 3. When using at a higher revolution (over 10,000min-1), refer to the table to adjust the balance of MEC and suitable arbor. M67
