WNT inserts tackle superalloys

The HCN5110 (for titanium and its alloys) and HCN5115 (for super alloys such as Inconel and Hastelloy) feature the brand new M34 style chipbreaker, which creates an extremely sharp cutting edge and facilitates the evacuation of swarf from the cutting zone. These features greatly reduce the cutting forces and the heat build-up during cut. And, with depth of cuts of up to 4.5 mm, they offer potential for volume metal removal. Both insert types feature a TiAlN PVD coating that creates improved wear resistance, due to the coating's friction-reducing qualities and, in both cases, the carbide substrate delivers specific benefits when machining these materials. In the case of HCN5110, the carbide is in the ISO k10 range and creates a very hard and abrasion resistant substrate, whereas HCN5115 uses an ISO K15 grade of carbide to give high edge stability. HCN5110 and HCN5115 inserts are available in a variety of standard ISO insert shapes and sizes, including CNMG, DNMG, SNMG, TNMG VNMG and WNMG and, depending on the insert style and size, maximum depths of cuts of between 2 mm and 4.5 mm at feeds up to 0.45 mm/rev are possible.
