Sumitomo expands DGC milling cutter body range to accept eight and 16

With its light hone and medium CBN content (65 per cent) this grade is well suited for higher cutting speeds (800-980 sfm) in super alloys such as Inconel-718.

WBH20, with 50 per cent CBN content and optimized grain structure, is wear-resistant at medium cutting speed. With a T-land of 0.008 in. x 20° it was developed to enable components of hard ISO H materials up to 65 HRC, to be grooved efficiently and with low wear during either smooth or interrupted cut. Typical areas of application include the automotive and agricultural equipment industry, but also general machining and energy.

The MD133 milling cutter offers high process reliability and maximum productivity with an optimal metal removal rate with reduced machining times.

WBS10 grade was developed for aerospace materials, specifically super alloys from ISO-S materials group. It's designed for grooving materials such as Inconel on engine components, and in the oil, gas and energy industries, as well as general mechanical engineering.

Walter introduces its latest CBN insert grades. WBH20 is a grade well suited for ISO-H Group of material such as for hard turning applications. WBS10 is well suited for ISO-S materials, specifically nickel-based (such as Inconel), iron-based (such as Udimet) or cobalt-based (such as Hayens).
