KCRA Double-Sided Ceramic Round The KCRA is our newest (patent pending) indexable milling ceramic round platform specifically engineered to maximize productivity while machining high temperature

2 KCRA Double-Sided Ceramic Round The KCRA is our newest (patent pending) indexable milling ceramic round platform specifically engineered to maximize productivity while machining high temperature alloys. Featuring double-sided inserts with increased tooth density, KCRA provides the highest material removal rate with the most effective machining. Kennametal Ceramics dramatically increase your productivity when machining Ni- and Co-based alloys. Features and Benefits First choice for face and shoulder milling high-temperature alloys. Higher material removal rate due to fine pitch cutters. Secure clamping system improving process stability and reliability. Effective air coolant feature. Better chip flow and increased insert tool life. Flat-top geometry for roughing applications in Ni- and Co-based alloys. -EGN Lower cutting forces. -TGN Strongest cutting edge. *Alternative for unstable situations. 2

3 Unique Air Coolant Feature Improved chip flow. Reduces chipping effect on cutting edges. Patent pending. Secure Clamping System Improved stability. Increase process reliability. Facilitates insert change. Thinner Ceramic Round s Increased MRR capabilities. Reduces cutting forces. Improved cost per edge. 3
