ATI Stellram has released the new XE solid carbide endmill engineered specifically for machining exotic and difficult to machine materials. The advanced geometric design featuring deep flutes and robust high helix cutting edges is the result of our continuous improvement program in aerospace machining. The tool is designed to run faster, run cooler and, with through tool coolant and deep flute design, evacuate chips more efficiently. Stellram XE endmills feature a longer shaft for maximum clamping and reach and to help minimize vibration. XE endmills are manufactured from a wear resistant submicron substrate, and are coated with PVD Nano TiAlN. The design of the Stellram XE endmill enables the tool to slot and profile to higher radial and axial engagements and run at higher surface speeds and feeds in the most difficult to machine materials. The net effect of all these enhancements is that the Stellram series of XE solid carbide endmills removes more material, faster and lasts longer in difficult to machine materials.
