The new end mill requires no stops for tool changes, the company said.
PITTSBURGH—Kennametal Inc. recently expanded its line of HARVI™ Solid Carbide End Mills with a new 8-flute design option that requires zero stops for tool changes, the company said in a release.
The company described its new HARVI™ IV 8-Flute End Mill as a high-performance and versatile end mill for machinists in aerospace and defense, medical, energy, and general engineering applications that require maximum output when cutting a range of difficult-to-machine materials.
“Our first 8-flute end mill will move customers from one challenging cut to the next without having to stop for tool changes,” said Scott Etling, Kennametal’s vice president of marketing, global product management, in the release. “Machinists need to achieve high productivity when working on tougher materials, while remaining cost-effective. Our new HARVI IV 8-Flute End Mills deliver just that and were designed especially for roughing and finishing applications that require a combination of flexibility and safe processing.”
While similar products often work on one type of material, HARVI IV 8-Flute End Mills are reported to have an innovative design that supports cutting across difficult applications, such as high-temperature alloys, stainless steels, steels, and hardened materials. Its design is also said to deliver higher metal removal rates and process stability with an internal coolant supply that clears away chips, even in deep cavities.
Kennametal said the launch of the new HARVI IV 8-Flute End Mills coincides with the company’s newly announced end milling grade KCSM15A. This innovative coating technology reportedly provides “extended tool life for users and the best wear resistance in Kennametal’s history of solid carbide end milling.”
