MILLING Page 3 / 4 JANUARY 2012 METRIC 2012 New Product Announcement The chip splitting edge causes a wide chip to be divided into small segments that significantly improve chip evacuation and handling. Chip splitting reduces cutting forces and thus power consumption. It diminishes thermal loading on the milling cutter and considerably improves vibration dampening. The main application of these new inserts is productive rough milling of deep shoulders, cavities and edges, especially when extended flute cutters are used. Reduced heat generation during cutting is very important, especially when...
