Chip Breaker Series offers 11 grades.

Press Release Summary:




Designed to help increase number of parts per edge, Beyond(TM) screw-on positive insert chip breakers - FP (Finishing Positive), MP (Medium/Roughing Positive), MW (Flat Top) - include 11 grades optimized for steel, stainless steels, and cast-iron applications. All share features such as micro-polished edges that promote edge toughness, post-coat treatment that reduces depth-of-cut notching, and fine-grained alumina layer that enhances coating integrity at higher cutting speeds.

New Beyond(TM) Screw-On (Positive Insert) Chip Breakers Increase Tool Life up to 250%



- MANY More Parts Per Edge -

(LATROBE, PA) - The new Beyond(TM) 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.

"These new chip breakers are the state of the art in tool design and production," says Ujjwal Baid, senior product manager at Kennametal. "Dimensional tolerances are tighter by 50% for improved indexability and tool life is up to 250% higher across a range of cutting parameters in turning steel, cast-iron, stainless steel, and high-temp alloy work-pieces. This means many more parts per edge for a large number of manufacturers."

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.

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 inserts, 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.

"In one test, an automotive manufacturer was performing internal diameter (ID) turning on grey-iron engine block castings with varying depths of casting scale," Baid says. "The new FP inserts showed an increase of 215% in parts per edge without changing speed, feed, or depth of cut. These tools are a great opportunity to improve productivity and efficiency for numerous manufacturing industries."
