ATI Stellram designed the 4E turning geometry to meet the demands of machining aerospace-type components manufactured from high nickel, high cobalt and titanium-based alloys. Available in grade SP0819, the inserts use an approved aerospace substrate and are enhanced with a nano-TiAlN layer PVD coating.

Combining a super-hard coating with a micro-grain carbide substrate significantly improves heat and wear resistance in high-temperature alloy machining, the company says. This can enable longer tool life and higher productivity.

For versatility, the inserts are designed to machine a variety of materials. This can reduce shop inventory, operator error and cost.
