WBH20 is a grade well suited for ISO-H Group of materials while WBS10 is well suited for ISO-S materialsClick image to enlargeWBH20 and WBS10 CBN insert grades from Walter Tools deliver optimum surface quality, high process reliability, and extended tool life in grooving operations on the toughest materials.

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).

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 grooving of hard ISO H materials up to 65 HRC 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.

WBS10 grade was developed for aerospace materials, specifically super alloys from ISO-S materials group. Among other tasks, it excels in grooving materials such as Inconel on engine components, and in the oil, gas and energy industries, as well as general mechanical engineering.
