Solid End Mills are Suitable for Heavy-Duty Roughing Steel, Stainless Steel

Sandvik Coromant is expanding its offering of CoroMill Plura HD solid end mills for heavy-duty roughing in steel and stainless steel with two new grades. This new generation of grades features the Zertivo 2.0 coating, which combines high productivity with an exceptional metal removal rate and high process security.

CoroMill Plura HD is Sandvik Coromant’s optimized solution for heavy-duty applications up to 2×D in steel and stainless steel (ISO P and ISO M), offering safe and efficient solid end milling. The new Zertivo 2.0-coated grade further improves tool life, process security and productivity. 

“With Zertivo 2.0, we are applying our comprehensive knowledge in coating technologies to our solid round tools,” says Antti Wikström, global product manager, solid end mills, at Sandvik Coromant. “This gives us an opportunity to offer unique, custom-made coatings that can handle our customers’ machining challenges with superior performance and tooling efficiency.”

The new grades enable a 30% increase in cutting speed recommendations for the primary ISO P and ISO M application areas, as well as secondary ISO K and ISO S materials, thanks to their optimized flute shape, which offers effective chip evacuation. The grades designed for stainless steel machining come in two variants: one with internal coolant for improved temperature control and chip flow, and one without internal coolant.

The standard assortment offers diameters from 2–25 mm, a 2×D depth of cut, 4 to 5 teeth and a ramping angle of 5° or 7°. Tailor made options are available within the Customized Solutions range.
