The HSSCo8 end mills are available in different types and finishes, with both parallel and Morse taper threaded shank , with bright finish and WIN coating (a special coating created by WSG). The PM HSS end mills have a AlCrN coating instead. The other tools in HSSCo8, like the dovetail, inverted dovetail and corner rounding cutters, the T-slot, the side and face milling cutters, the Woodruff keyseats milling cutters and the shell cutters series, all have a bright finish. In the solid carbide end mills section, the standard tools are distinguished from the high performing cutters of the Evolution line by High Speed Cutting (HSC) and High Performing Cutting (HPC). The main coating is TiAlN (Titanium Aluminium Nitride), but the end mills for aluminium are bright finished or coated in Zirconium Nitride (ZrN), whereas the end mills for dry processing of the Evolution series may have the innovative NaCrO (TiAlN nanocrystals) coating. Worthy of note are the HSC and HPC end mills with 35°-38° variable flutes suitable for both roughing and finishing processes. Pay attention to the "mini" end mills with smaller diameters, the corner radius end mills range, the roughing end mills with chip-breaker and the 50° flutes end mills for super-finishing.
