HARVI I TE from Kennametal, the latest Four-flute, solid carbide end mill delivers superior performance for steel, stainless steel, high-temperature alloys, and cast iron. With a basal new design, the HARVI I TE delivers phenomenal performance in a broad range of materials, including steel, stainless steel, high-temperature alloys, and cast iron -with tool life to match and reduced cutting forces. This game-changing tool can be used on any machining center or mill-turn center in the shop.
The HARVI I TE persistently surpassed competing for four-flute end mills in both wet and dry machining tests on a variety of materials and applications, with extraordinary tool life in many cases. It performs exceptionally well on heavy roughing and finishing cuts alike – from deep cavities and full-width slots to shoulder and dynamic milling.

HARVI I TE was designed by Kennametal engineers to address four key problems that scourge more than 90% of all milling applications: chip evacuation, tool deflection, corner stability, and breakage due to radial cutting forces. HARVI I TE is dependable, lasting and versatile enough to tackle the lion´s share of milling applications.
Look at chip evacuation. The HARVI I TE has a creative flute design that helps curl and break chips into manageable pieces, while a series of chip gashes within the flute lift those chips up and away from the workpiece. Both serve to promote coolant flow, phase out chip re-cutting, and improve tool life. A twisted end face and unique gashing further promote chip evacuation but are also responsible for the HARVI I TE´s brilliant ramping and plunging capabilities.
Tool deflection is reduced thanks to the tool´s parabolic core, as well as an eccentric, faceted relief along the entire flute length that automatically lowers cutting friction. This relief also increases edge strength, making the tool an an adaptable solution.

Together with a variable helix angle and asymmetric flutes, it dampens vibration before it can negatively affect machining operations. "The HARVI I TE improves process stability, surface quality, and chip evacuation," said Fiedler. "Most importantly, it maintains these benefits even at increased feeds, speeds, and depths of cut – delivering maximum metal removal, tool life, and productivity."
Much of the machining magic happens right here, with the creative twisted end face of HARVI I TE. Increasing corner stability, enabling soft cutting action even at highest ramping angles. For more details visit www.kennametal.com
