HARVITM Ultra 8X Helical Milling Cutter
Imagine burying a roughing tool in a block of Ti-6Al-4V titanium and ripping away more than 1,000 cm3 (61 cubic inches) of material in just one minute. If you'd been at a recent test of Kennametal's new HARVITM Ultra 8X helical milling cutter, you'd have seen exactly that. Using a 95 mm (3.74 in.) axial depth of cut, 20 mm (0.78 in.) radially, and a feed rate of 423 mm/min. (16.65 ipm), the 80 mm (3.15 in.) diameter HARVI Ultra 8X plowed through this difficult aerospace superalloy for nearly 3 minutes straight without flinching.
