Kennametal has announced the latest addition to its best-selling HARVI line of high-performance solid end milling tools, the HARVI I TE four-flute solid carbide end mill. The HARVI I TE delivers performance benefits in a broad range of materials, including steel, stainless steel, high-temperature alloys and cast iron – with tool life to match. And thanks to significantly reduced cutting forces, this tool can be used on any machining center or mill-turn center in the shop. 

“The HARVI I TE consistently outperformed competing four-flute end mills in both wet and dry machining tests on a variety of materials and applications, with unprecedented tool life in many cases,” said Bernd Fiedler, manager, solid end milling. “It performs exceptionally well on heavy roughing and finishing cuts alike – from deep cavities and full width slots to shoulder and dynamic milling.”

Kennametal engineers designed the HARVI I TE to address four key problems that plague more than 90% of all milling applications: chip evacuation, tool deflection, corner stability, and breakage due to radial cutting forces. The result is a tool that’s durable and versatile enough to tackle the lion’s share of milling applications.

“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.”
