Chip Breakers, Screw-On (Positive Insert)

The new Beyond line of high-performance turning products from Kennametal include 11 new grades for improved productivity in steel, stainless steels, and cast-iron applications. The company has now introduced new screw-on positive insert chip breakers – FP (Finishing Positive), MP (Medium/Roughing Positive) and MW (Flat Top) – that are showing up to 250% longer tool life across a range of applications and materials. FP (Finishing Positive) chip-breaker inserts have a proprietary chip groove that results in lower cutting forces and a unique nose design that avoids overcrowding of chips in the nose radius area. This optimises chip control while at the same time permits higher metal removal rates at lower cutting forces. MP (Medium/Roughing Positive) chip breaker inserts are suitable for chamfering applications and are also excellent in spindle boring due to high-strength edges for increased depth of cut. The flat top MW Beyond insert not only provides positive cutting, but also shows consistent chip control in short-chipping materials like cast iron. Along with the UF (Ultra fine Finishing) chip breaker insert, which is already available in Beyond grades, this new screw-on platform covers the entire range of machining needs. All these new screw-on inserts share the breakthrough performance characteristics of the entire Beyond line – micro-polished edges that improve edge toughness, proprietary post-coat treatment that reduces depth-of-cut notching, and a fine-grained alumina layer that enhances coating integrity at higher cutting speeds. Kennametal Inc is a leading global supplier of tooling, engineered components and advanced materials consumed in production processes. The company improves customers' competitiveness by providing superior economic returns through the delivery of application knowledge and advanced technology to master the toughest of materials application demands.
