Warning about max. revolution indicated on main body Warning Please observe below precautions fully. Failure to observe the precautions may cause serious damage to human body.Revolution (min -1)Balance quality grade G ISO 1940-1/8821 (JIS B0905)
1. Do not use the end mill or cutter at the maximum revolution or higher since the centrifugal force may cause inserts and parts to scatter or the body may be damaged even under no load.~20,000G16
2. For actual practical revolution, please set within recommended cutting condition.~30,000G6.3
3. When using at a higher revolution (over 10,000min-1), refer to the table to adjust the balance of MECX and suitable arbor.30,000~G2.5
