Kennametal has expanded its HARVI I TE series with the HARVI I TE four-flute ball-nose end mill. Designed for productive 3D roughing and finishing operations, the new cutter delivers lower machining cost through maximum metal removal in a broad range of materials, says the company.

The HARVI I TE ball-nose end mill features a novel proprietary relief that requires a closer look. In the most critical area – the ball-nose section – a wavy contour shapes the rippled relief that provides improved coolant flow into the cutting zone. The result, according to Kennametal, is maximised productivity and tool life in 3D milling operations.
In addition, the rippled relief enables higher feeds and speeds, as well increased depths of cut, thanks largely to advanced vibration damping and lower cutting forces.

On the outer diameter, the relief changes its shape, and turns into the eccentric faceted relief. Kennametal says this eccentric faceted relief provides exceptional edge strength, geometric accuracy, lower cutting forces and makes the HARVI I TE four-flute ball-nose end mill highly versatile.

Further geometry advancements of the square-end styles – including a twisted end face, chip gashing and a variable helix angle – also feature in this new solid-carbide end mill.

Kennametal is making the HARVI I TE ball-nose end mill available in two different lengths, both with a diameter range from 2 to 20 mm.
