on the steel product pages A248 & A250 . For security use a new screw each time. This tool must only be used for the following applications: Face milling, shoulder milling, slotting and pocketing.
- Check the balancing of the – assembled tool – cutter
body, inserts and attachment.
- Before start up, note the maximum RPM engraved on

The maximum RPM is linked to a precise balancing value. designed and balanced to G6.3 at 30,000 rpm for diameters 50mm and below. Diameters larger then 50mm are balanced to G6.3 at 24,000 rpm.
