Solid Carbide Milling Cutters reduce micro fracturing.

Press Release Summary:

Designed for stability and to minimize likelihood of micro fracturing, Walter Prototyp Supreme MB265/MB266 feature coolant strategy without radial exits, V-cutting edges that increase ramping angle, and one cutting edge to center. Engineered primarily for use with ISO N material group, these milling tools come in WJ30UU (uncoated) grade; Supreme MB265 is also available in WJ30CA (CrN coated) grade. Design promotes productivity due to metal removal rates, tool life, and process reliability.

Walter Expands its Range of Solid Carbide Milling Cutters

The new Walter Prototyp Supreme MB265 and Supreme MB266 solid carbide milling cutters deliver high productivity due to their high metal removal rates, robust tool life and higher process reliability.

Waukesha, WI — Walter has introduced the Walter Prototyp Supreme MB265 and MB266 solid carbide milling cutters, two new milling tools that boost productivity due to their high metal removal rates, while also increasing process reliability thanks to design features that act to enhance stability while simultaneously decreasing the likelihood of micro fracturing.

In keeping with its practice of continuous product improvement, these two new mills replace and expand the technical capabilities of Walter’s Sky•tec™ milling cutters. One of the key design features of the new mills is their coolant strategy. The conventional approach with this type of tool is to have both axial and radial coolant exits. However, this approach tends to make the tool less reliable, largely because radial exits are produced by an EDM machine, often leading to micro fractures. With the Supreme MB265 and MB266 careful engineering of the axial coolant exists has allowed the radial exits to be removed, eliminating this problem. In addition, both of these new solid carbide milling cutters feature V-cutting edges that result in more ramping angle as well as one cutting edge to the center.

The new solid carbide milling cutters are engineered primarily for use with the ISO N material group which includes alloys of wrought aluminum, cast aluminum, and magnesium, as well as bronze and brass. Applications include shoulder milling, slot milling, interpolation milling, and plunge milling in general metalworking as well as aerospace. The Supreme MB265 is available in grades WJ30UU (uncoated) and WJ30CA (CrN coated). The Supreme MB266 is available in grade WJ30UU (uncoated).

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.
