CA115P CA125P Inserts

Versatile and Specialized

Kyocera has designed the CA115P/CA125P series to provide extended tool life and superior performance in a variety of machining scenarios. The CA115P is ideal for continuous to light-interrupted machining, offering highly efficient and precise results. CA125P is optimized for continuous to heavy interrupted machining, making it a versatile general-purpose grade for steel machining.

Under the Surface

The newly developed proprietary coating and carbide substrate of the CA115P/CA125P series offers unmatched wear and fracture resistance. The coating properties on the rake and flank faces are optimized to provide excellent wear resistance. The black and gold appearance and stark contrast are beyond cosmetic in nature. The black rake face is composed of a highly uniform alumina layer reducing wear, suppressing cratering, and diminishing fracturing. The striking gold flank includes a hard surface layer, a highly uniform alumina layer, and a unique TiCN layer while also allowing easy edge defect detection. All these layers on the flank work together to improve the wear-resistant properties of the insert and to suppress surface abrasion. Below the coating, the new carbide substrate displays enhanced resistance to plastic deformation and exhibits increased temperature resistance.
