Walter USA Announces New Grade to its Walter Valenite Indexable Milling Lineup



Walter USA, LLC has added a new grade to the Walter Valenite indexable milling grade family. The existing universal WKP35S grade is now joined by WKP25S, a CVD-Al2 O3 -coated insert designed to permit higher feed and speed rates and higher rates of metal removal, particularly in the machining of steel and castings, the company said.

"This newly developed Tiger-tec Silver WKP25S milling/cutting grade is designed to maximize productivity through its ability to process all steels at high cutting speeds as well as with high average feed rates, yet increase process reliability through its high wear resistance, toughness and shock resistance," said a Walter spokesperson. "Its proven bicolor coating is designed to offer efficient wear detection. In addition, the new grade racks up similar improvements in the machining of tool steels with strengths greater than 1,000 N/mm2 and when used in difficult conditions such as wet machining or machining materials with high tensile strength.

"The new grade also excels in the machining of gray cast iron or cast iron containing vermicular graphite. It can process these hard to cut materials at average to high cutting speeds and average feed rates. The new grade is also suitable for difficult cutting conditions so often encountered when machining these materials, such as fluctuating material removal or severely interrupted cuts.

"Currently, Tiger-tec Silver WKP25S is available for tools in the Walter Valenite Xtra-tec range, including: face and shoulder mills F4041 and F4042; side and face mills F4053, F4153 and F4253 and porcupine cutters F4038, F4138, F4238 and F4338. Other inserts for drilling and turning are also in development."
