VariMill Chip Splitter



Hanita, a WIDIA brand, has released the for dynamic and trochoidal milling operations in steel, stainless steel and heat-resistant superalloys. The delivers higher metal removal rate (MRR) by separating long, undesirable stringy chips from deep cavities and dynamic milling paths by cutting material into shorter, more manageable sections.

This high-performance 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.

"The Hanita helps machinists cut faster and longer by enhancing the ability to flush or blow away stringy chips from deep axial cuts without forming clumps of intertwined swarf. This is very important to avoid re-cutting of chips, which could damage the cutting edges and shorten tool life, Additionally, the ability to rough and finish with the same tool provides great benefit in cycle time and inventory management, both in the tool crib and the machine's carousel," said Steve George, Senior Manager of Hanita Product Engineering.

End Mills are available in 5- and 7-flute configuration in 1/2" to 1" inch standard dimensions in WP15E and WS15PE grades. According to the company, the end mill can cut up to 4.5xD, achieve high feedrate per tooth values, reduce radial forces and improveme MRR and overall tool life without compromising surface quality.

The 5-flute chip splitter maximizes performance needs when machining steel materials and the 7-flute chip splitter is suited for machining stainless steel, and heat-resistant superalloys such as 17-4PH, Inconel and titanium.
