Difficult milling made easier

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.

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 3 to 20 mm – feature an optimised 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, says Dormer Pramet. The S262’s corner radius provides a more precise finish and optimises 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 workpiece and deliver 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 workpiece, and 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 series also features an optimised cutting-edge design and an AlTiN coating for high hot hardness and oxidation resistance.
