Kennametal's solid carbide HARVI I TE four-flute ballnose end-mill supports higher speeds and feeds

​Kennametal has introduced an expansion to the HARVI I TE series, the HARVI I TE four-flute ballnose end-mill.

Designed for highly productive 3D roughing and finishing operations, it delivers lower machining cost through maximum metal removal in a broad range of materials.

The HARVI I TE ballnose end-mill features an innovative proprietary relief that has in the most critical area - the ballnose section - a wavy contour that shapes the rippled relief that provides improved coolant flow into the cutting zone.

The rippled relief enables higher feeds and speeds, as well as increased depth of cuts by advanced vibration damping and lower cutting forces.

On the outer diameter, the relief changes its shape and turns into the eccentric faceted relief. The eccentric faceted relief provides exceptional edge strength, geometric accuracy, lower cutting forces and makes this end mill series very versatile.

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

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