Current developments in inserts (coated their improved capability for high speed cutting is remarkable. However, the results are based on using these inserts with high-speed cutting conditions (their performance is reduced when used for medium or low cutting speeds). The ZMAC Boring Head has been designed to optimise this new high-speed cutting technology. Cutting data M/C ： VC8 Holder ： NC5 － 63 － Q26 － 50 SP26 － 12 － 30 & CBN) and
