X-Feed™ End Mills for High-Feed Milling X-Feed X-Feed significantly reduces manufacturing time machining heat-treated steels up to 67 HRC hardness, having 50% more effective cutting edges than regular solid carbide tooling. X-Feed combines roughing and semi-finishing into one operation by taking shallow depths-of-cut at extremely high feed rates, maximising Metal Removal Rates (MRR). X-Feed, which has a 3 x D neck and extended reach design, is perfectly suited for pocketing using 3D machining techniques such as ramping and helical interpolation. During face milling, the proprietary front-end geometry of X-Feed is entirely in contact with the workpiece, providing up to 55% engagement compared to the regular 5–10% provided by ball nose-type tooling. • Proprietary 6-flute design for high productivity. • One tool for roughing and semi-finishing operations. • Covering hardened materials ranging from 37–67 HRC with two dedicated geometries. • Custom solutions tailored for machining titanium and other high-temperature alloys available. Necked shank providing extended reach in deep cavities. Proprietary geometry maximising Metal Removal Rates (MRR). 6-flute design allowing helical AlTiN coated for maximum tool life. ramping, circular interpolation, and face milling. O150 widia.com
