Milling Cutters

The new MD133 Supreme milling cutter from Walter, designed specifically for dynamic milling, delivers increased process reliability, particularly during unmanned operation. It reportedly boosts productivity thanks to a higher metal-removal rate and a reduction in machining time.

DUO-LOCK from Kennametal Inc. is a modular endmill with the performance of solid carbide. It uses a proprietary, double-cone locating surface similar to that of Kennametal’s KM or KM4X tooling design, assuring “not to exceed” radial runout values of 5 μm (.0002 in.) and Z-axis coupling repeatability of 10 μm (.0004 in.) or better.

Customers have been asking for a new carbide grade to machine titanium 6Al4V at higher cutting speeds compared to increasing feed rates or increasing depth of cuts in that result in increased cutting forces imposed on the workpiece, fixtures and machine spindles. The KCSM40 grade has an advance cobalt binder that provides thermal fatigue resistance without sacrificing the toughness customers have experienced with KC725M or X500.

Walter has introduced the Walter has introduced the M2471, a copy milling cutter with excellent cost efficiency thanks to its high metal-removal rate -- even on low performance machines, coupled with lower cutting material costs resulting from its eight cutting edges (four per side) per insert. These 12 mm positive cutting geometry, round inserts with negative basic shape feature Walter's Tiger·tec Silver coating, ensuring maximum tool life.

Sandvik Coromant has unveiled a new, high-feed version of the CoroMill 745 facemilling cutter, featuring a 25° entering angle for additional productivity gains when milling steel and cast iron workpieces. The new, high-feed version facilitates even higher metal-removal rates in applications with depths of cut up to 2.8 mm (0.110 inch).

Seco has further expanded its selection of disc milling inserts and cutter bodies to meet customer demands for reliable, high performing cutters. With that, the company has introduced the 335.14 small-diameter exchangeable head system, 335.16 cutter for T-slot operations and cassette versions of its 335.25 cutter that incorporate round inserts.

Walter has introduced the M2136, a multitooth close-pitch finishing cutter that features a high degree of process reliability coupled with superior cost effectiveness, particularly with cast iron, thanks in part to its eight cutting edges per insert. These stable, negative inserts promote not only stability but also ease of handling as well as leading to high levels of surface quality during the finishing process.

A heavy-duty ID clamping pipe milling end prep tool that can J-prep bevel, face and bore all hard pipe alloys in preparation for orbital welding is available from ESCO Tool. The Esco Prepzilla Millhog ID clamping end prep tool is offered with a wide selection of cutting blades, including a J-preparation blade that creates a consistent contoured radius and clean neck for orbital welding.
