New BEYOND Screw-On (Positive Insert) Chipbreakers Increase Tool Life Up to 250%

(LATROBE, PA) – The new Beyond™ line of high-performance turning products from Kennametal launched at IMTS 2008 included 11 new grades for improved productivity in steel, stainless steels, and cast-iron applications. Now the company is introducing 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 optimizes chip control while at the same time permits higher metal removal rates at lower cutting forces.

The flat top MW Beyond insert not only provides positive cutting, but also shows consistent chip control in short-chipping materials like cast iron.

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.
