New Mill for Shoulder Milling

Kennametal has launched a New Mill 4-15™ Platform that provides best-in-class shoulder milling. The innovative double-sided design has four cutting edges; options available for 90-degree shoulder milling applications. Experienced manufacturers know that when milling, three main considerations predominate – metal removal rate, tool life, and surface finish. All three are critical to successful metalworking, but often one will predominate. Manufacturers facing parts requiring 90-degree shoulders also know that achieving true 90-degree shoulders and minimizing the scallop or step marks between passes absolutely requires a high-performance cutter. The new Mill 4-15 platform from Kennametal is that best-in-class system. Mill 4-15 features a double-sided insert with four cutting edges for effective cost per edge and able to take up to 15mm [.590”] depth of cut, while a unique cutting edge design assures positive contact through 90-degree milling and virtually “stepless” solution for stepping-down applications. In addition, an integrated wiper facet achieves best-in-class surface finishes. Mill 4-15 inserts will be available precision ground or moulded inserts with corner nose radii from 0.4 mm to 2.4 mm. Topographies include GE with a high positive rake, effectively lowering cutting forces while reinforced cutting edge emphasizes cutting-edge strength for medium to heavy applications. Mill 4-15 cutter bodies are manufactured to very tight tolerances. Multiple cutter body options, including screw-on, cylindrical shank end mills, Weldon shank end mills, and shell mill cutters with effective internal coolant feature are available.
