Widia VSM17 90° shoulder-milling tools boast impressive material removal rates and chip clearance

The Widia VSM17 line of 90° shoulder-milling tools offers an aggressive ramping angle of up to 8.8° with a well-guided internal coolant supply, both of which combine to generate impressive material removal rates and chip clearance. ITC is the UK supplier.

The steel VSM17 tool bodies are available with screw-on, Weldon and cylindrical end-mills from 25 to 40 mm diameter with regular and long shanks, shell-mills from 40 to 160 mm and the M4000 cartridge milling system with diameters from 125 to 315 mm. The various tool bodies incorporate an optimised chip gash that bolster stability, chip removal and cutting efficiency.

This latest addition to the Widia 90° Victory Shoulder Mill (VSM) Series generates low horsepower consumption and offers versatility and a soft cutting action that makes it the choice tool for everything from light, precise machining to medium roughing.

The two-edged 16 mm inserts employed incorporate an embedded wiper facet for excellent surface finishes, an additional margin on the clearance face that strengthens the cutting edge and a super-positive rake design that generates a soft cutting action. Furthermore, the VSM17 inserts extend tool life via multiple corner nose radii from 0.4 to 0.6 mm, with additional radii options available for specific aerospace applications.

The inserts are offered in a complete range of grades that deliver longevity and consistent performance when machining cast iron, steel, stainless steel, aluminium, aluminium alloys and a comprehensive variety of additional materials. For the advanced machining of aerospace grade materials, Widia has added its newest WS40PM grade to the VSM17 line. This multi-layered PVD AlTiN-TiN coated grade for wet and dry machining improves chemical and abrasive wear resistance, minimises thermal cracking and opposes fatigue to a level far beyond that of alternate indexable cutting tools.

Each of the insert grades is offered with the option of the ALP, ML, MM and MH insert geometries. The ALP is a peripheral ground geometry for the rough to finish machining of aluminium alloys whereas the ML is designated for light to finish cutting on stainless and titanium. Both geometries generate low cutting forces and perform particularly well during finish machining, while the MM and MH are general and heavy duty cutting grades for a multitude of material types.
