Setting The Benchmark For Machining Steel

Walter launches new MD340 & and MD344 Supreme solid carbide milling cutters

Despite a growing trend towards lightweight construction, steel machining still represents a significant market share. With the MD340 and MD344 Supreme solid carbide milling cutters, Walter is launching two new tools for ISO P materials. The MD340 Supreme (dia. 2–25 mm or 1/16–¾") is specifically designed for roughing, full slotting and dynamic milling of steel materials. The extensive product range with three, four or five teeth makes it suitable for universal application. The MD344 Supreme four-edge cutter with its special face geometry (dia. 6–20 mm) is designed for 90° plunging or ramping. The solid carbide milling cutter therefore sets new standards, particularly when it comes to plunging and pocket milling in a single operation. Mass producers in particular can shorten the machining time due to fewer tool changes, while required tool spaces in the machine and reconditioning costs are also reduced because no additional boring tool is needed.

Both of these steel specialists boast a multi-layer TiAlN and ZrN coating developed in-house at Walter, as well as a reduced neck. As a result, the Supreme milling cutters machine ISO P materials at the very highest level. The MD344 Supreme is even considered the benchmark for opening up and machining pockets and cavities using the same tool. The main benefits of the MD340 and 344 Supreme milling cutters are their high cost-efficiency and long tool life in ISO P machining. The variable helix, pitch and number of teeth, all of which are perfectly coordinated, ensure exceptional performance and operational smoothness. What's more, the helical pitch is adapted to the number of teeth, which improves the surface quality.
