Kennametal's A4 groove and turn inserts, made of KYON 3500, enable high-productivity machining of gray cast iron designed for high speed grooving applications.
The grade is an advanced silicon nitride ceramic grade developed by Kennametal. In tests, its higher toughness and the advanced insert design resulted in higher feed rates. Products that can benefit from the inserts include brake discs, brake drums and wheel hubs in the automotive market as well as valve components in general engineering applicaitons.
The A4 double-ended insert is available in both rectangular and full-radiused styles. Available cutting widths range from 3 mm to 8 mm (0.125" to 0.250").
