Ball Nose End Mill is Optimized for Semi-Finishing to Profile Finishing

Sandvik Coromant has expanded its CoroMill Plura solid end mill family with a new concept — CoroMill Plura ball nose — optimized for semi-finishing to profile finishing operations in ISO S applications. This release introduces two new product geometries, optimized for titanium and HRSA workpiece materials, respectively, with productivity, extended tool life and process security requirements in mind.

Outside of machining blades and forged structural components, CoroMill Plura geometries are “also a solid choice for application areas outside of the aerospace segment, such as the medical and automotive sectors,” says Dr. Markus Groppe, global product and digital application manager for solid carbide end milling tools at Sandvik Coromant. “Additionally, with secondary application areas of hardened steel for the HRSA assortment and stainless steel for the titanium assortment, the six flute tools ensure the highest productivity and tool life for all types of mold and die applications.”

Specific care has been put into the cutting tool design. It feature a newly developed face geometry to avoid unfavorable cutting conditions in the center, uneven tooth pitch for dynamic stability and vibration control, as well as new Zertivo 2.0 grades — developed specifically for the workpiece application areas — for improved wear resistance and tool life.

Featuring up to six flutes, CoroMill Plura ball nose enables higher feed rates without compromising the surface quality, meaning reduced machining times and a lower cost per part. 

The standard assortment includes dedicated grades for titanium and HRSA, diameters ranging from 3-20 mm and 0.125-0.75", four to six flutes, 1.5×D depth of cut and usable lengths of 3×D and 5×D. Should the standard assortment not align with specific customer needs, Sandvik Coromant offers a wide selection of customized solutions to address unique requirements.
