Kennametal Inc. is expanding its turning portfolio with inserts and cutting tools that broaden its machining capabilities in the small parts and medical machining space. TopSwiss Micro Boring Solid (MBS) tooling and KCU25B turning inserts are designed to improve output, enhance component quality, reduce errors and help users achieve accurate and clean results.

MBS tooling allows for the machining of small applications with greater versatility and flexibility while providing sharp cutting edges, low cutting forces and superior chip evacuation. This is said to result in longer tool life and optimized surface finishes. The latest in the TopSwiss lineup includes high-performance internal turning in bores as small as 0.3 mm (0.012"), precision-ground insert shanks for high accuracy and stability and over 1,100 standard items provide the right toolholder and insert for each application.

Additionally, the KCU25B turning inserts are said to provide a powerful roughing and medium machining metalcutting solution for aerospace and defense, energy, general engineering and transportation shops working with steels, stainless steels, cast iron and high-temperature alloys. Well suited for common turning, grooving and cut-off applications, KCU25B inserts also feature Kennametal’s KENGold physical vapor deposition (PVD) coating, which provides multiple layers of protection for better flank and chipping resistance.
