Kennametal Inc. has expanded its bestselling and best performing line of HARVI Solid Carbide End Mills with a new 8-flute design option that requires zero stops for tool changes.

Kennametal_HARVI IV 8-Flute End MillThe new HARVI IV 8-Flute End Mill is a high-performance and versatile solution 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.

Move from one challenging cut to the next with internal coolant channels and an 8-flute design delivering higher machining flexibility and process stability.

"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, vice president of marketing, global product management. "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 requires a combination of flexibility and safe processing."

While similar products often work on one type of material, HARVI IV 8-Flute End Mills' innovative design provides versatility that supports cutting across difficult applications like high-temp alloys, stainless steels, steels and hardened materials. Its design also delivers higher metal removal rates and process stability with an internal coolant supply that clears away chips even in deep cavities.

The launch of the new HARVI IV 8-Flute End Mills coincides with Kennametal's newly announced stainless steel, titanium and other high-temp alloys end milling grade KCSM15A. This innovative coating technology provides extended tool life for users and the best wear resistance in Kennametal's history of solid carbide end milling.
