A body is disclosed with a coating comprising one or more refractory layers of which one layer is an outermost smooth, shiny 110-textured alpha -Al2O3 layer. Said Al2O3 layer has a surface appearance almost like a polished Al2O3 layer. Coated tools show improved tool lives compared to prior art tools when used for machining steel or cast iron material preferably for near net shape machining. |
