Four-Flute Ball Nose End Mill with Rippled Relief Machines Versatile Material Range

Kennametal introduces an expansion to the Harvi I TE series, with the addition of a four-flute ball nose end mill. Designed for highly productive 3D roughing and finishing operations—including for mold machining—Kennametal says it delivers low machining cost through maximum metal removal in a broad range of materials.

The end mill’s rippled relief enables high feeds and speeds as well as increased depth of cuts by advanced vibration damping and lower cutting forces. The relief changes its shape on the outer diameter, turning into an eccentric faceted relief for exceptional edge strength, geometric accuracy and versatility.

Other geometry advancements in the square end styles —including a twisted end face, chip gashing and a variable helix angle—have also been engineered into this solid carbide end mill.

The Harvi I TE ball nose end mill is available in two different lengths (inch non-necked, metric with neck) both with a diameter range from 2-20 mm (1/16" to 1"). The regular length is the first choice for 3D copy milling operations, while the long version offers sufficient length-of-cut (up to 4sD) for many applications, including shoulder milling when wall and floor finishing is required.
