Cutting tool specialist Sandvik Coromant is expanding its range 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 specialized Zertivo 2.0 coating, which combines optimized productivity with process security and an increased metal removal rate (MRR).
CoroMill Plura HD is designed 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 is said to improve tool life, process security and productivity over previous versions.
“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.”
According to the company, the new grades enable a 30% increase in cutting speed for the primary ISO P and ISO M application areas, as well as secondary ISO K and ISO S materials, due 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, four-to-five teeth and a ramping angle of 5- or 7-degrees. Customized options are also available.
