Dormer Pramet’s family of solid carbide milling cutters for difficult to machine materials offers a variety of options from roughing through to finishing
The S2 assortment includes a range of neck options for deep milling and multi-flute designs to support numerous applications in tough steels, titanium and nickel. Its differential pitch cutters (S260, S262, S264), for example, reduce chatter and offer fewer tool offset adjustments, providing effective chip removal at high feed rates.
The trio of cutters – available in diameters from 3mm-20mm – feature an optimized cutting-edge to reduce chipping and prolong tool life. All have an AlCrN coating for improved wear and oxidation resistance. In addition, the S264 milling cutter has a robust corner chamfer on the end teeth to further reduce chipping and a roughing profile for greater removal rates. Also, the S262’s corner radius provides a more precise finish and optimizes performance, especially in ramping operations. Meanwhile, Dormer Pramet’s six to eight-flute cutters (S225, S226, S227) feature a high helix angle to keep the cutting edges constantly engaged with the work-piece. This results in clean, efficient machining and a high-quality surface finish.
Several neck options are available to support pocket milling, up to 8.8xD, by preventing contact between the shank and work-piece, eliminating the risk of vibration and scouring.
To support general milling applications, the company’s range of four-flute cutters (S216, S217, S218, S219) offer a reach up to 9xD. This range also features an optimized cutting-edge design and an AlTiN coating for high hot hardness and oxidation resistance. A special edge treatment provides a smooth and quiet machining process, further prolonging tool life.
Finally, an assortment of ball nose cutters (S229, S231, S233) are available in 1.5mm-16mm diameters, offering up to 8.3xD. As well as a special edge treatment to support smooth machining, its TiSiN coating provides improved wear and oxidation resistance in extreme cutting conditions.
