"Our first 8-flute end mill will move customers from one challenging cut to the next without having to stop for tool changes," says 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.
