End mills improve material removal rates

Seco Tools recently released two new solid-carbide end mills that improve metal removal rates in difficult-to-cut workpiece materials. The Jabro®-HFM JHF181 is suitable for high-feed milling of hardened steels and nickel-based alloys, while the Jabro-Solid2 JS564 and JS565 are suitable for roughing of steels, stainless steels, and titanium alloys.

With the new HXT coating, the JHF181 gains a hard layer that delivers advanced thermal protection and high wear resistance, the company states. It is available in 2-, 4-, and 5-flute options with cutting diameters from 0.0787 to 0.6299 in. and length options from 2xD to 7xD. This end mill also has through-tool coolant capability for diameters from 0.2362 to 0.4724 in.

The JS564 and JS565 have tapered cores and polished NXT coating. They provide a relatively high radial engagement while maintaining high feeds and speeds for optimized roughing passes, the company states. Furthermore, the positive frontal teeth geometries on these two end mills make them suitable for axial and helical interpolation operations.

A chip splitter on the end mills creates small chips when using long cutting lengths, ensuring the best possible chip evacuation.

They are available in 4- and 5-flute designs in numerous cutting diameters and lengths. The JS565 is also available without a chip splitter. For both tools, cylindrical shank diameters are available from 0.1181 to 0.7874 in., and Weldon shank diameters are available from 0.2362 to 0.7874 in.
