MC251 Solid Carbide Mill optimizes machining of stainless materials.

Press Release Summary:

Being solid carbide milling tool, MC251 increases tool life by up to 50% in austenitic stainless steels and nickel-base alloys. Tool operates best on machines having external coolant supply. Product uses asymmetrical helix angles between 35° and 38° which results in low susceptibility to vibration thereby increasing process reliability. Minimizing build-up on cutting edge, unit is coated with Titanium Aluminum Nitride which increases tool service life.

Original Press Release:

New MC251 Advance Family of Solid Carbide Milling Tools from Walter Boosts Tool Life and Process Reliability in Stainless Steel Machining

With its innovative design, tough carbide substrate and coating, the Walter MC251 Advance sets a new benchmark for stainless steel machining.

Walter has introduced the Walter Prototyp MC251 solid carbide mill, positioned with the Advance product line designation. Advance referring to mid-level performance and price. Advance tools are one part of a group of solid tools labeled either Supreme (high-level performance and price), Advance (mid-level performance and price) or Perform (low-level performance and price). The MC251 is a family of solid carbide milling tools that can increase tool life by up to 50 percent in austenitic stainless steels and nickel-base alloys.

The MC251 geometry has been designed to optimize the machining of stainless materials from the ISO M material group as well as for secondary applications in ISO S materials. The new MC251 tool family is engineered to operate most efficiently on machines having an external coolant supply.

A tough carbide substrate (WK40RC) is used to provide superior machining reliability. In addition, process reliability is boosted by the mills’ low susceptibility to vibration by incorporating asymmetrical helix angles between 35° and 38°. The tools’ coating, a proprietary recipe of Titanium Aluminum Nitride designed and produced by Walter, increases tool service life and minimizes build-up on the cutting edge.

Walter, a global leader in the metalworking industry with over 90 years of experience in precision cutting tools for milling, drilling, turning, boring and specialized tools, helps customers improve process reliability and increase productivity. With Regional Headquarters in Waukesha, WI, Walter markets its competence brands Walter Valenite, Walter Titex, Walter Prototyp and Walter Multiply through a strong network of distributors and field engineers across subsidiaries in the USA, Canada, Mexico, Brazil and Argentina.
