ATI Stellram’s XE solid-carbide end mills are engineered for machining exotic and difficult-to-machine materials. The geometric design features robust high helix cutting edges. The tools run faster, cooler, and evacuate chips more efficiently due to through-tool coolant and a deep flute design. A long shaft enables maximum clamping and reach, and it helps minimize vibration. The units are manufactured from a tough, wear-resistant submicron substrate and are coated with PVD Nano TiAlN. The design 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.
