Hanita, a Widia brand, has released the VariMill Chip Splitter end mill for dynamic and trochoidal milling operations in steel, stainless steel, and heat-resistant superalloys.

This end mill is designed with non-overlapping chip splitters along the flute cutting edges. The result is more efficient MRR, while maintaining the ability to make finishing passes. The unequally spaced design feature allows each sequential cutting edge to remove any remaining material left by the chip splitter of the previous flute. The tool’s design reduces breakage and makes it versatile enough for both roughing and finishing passes.

These tools are available in 5- and 7-flute configurations from ½ to 1 in. standard dimensions in both WP15E and WS15PE grades. The end mill can cut up to 4.5xD.

This tool enables high metal removal rates (MRR) by separating long, stringy chips from deep cavities and dynamic milling paths by cutting the material into shorter, more manageable sections.
