New 6, 8, and 10-mm grooving inserts and toolholders, a full line of width inserts, and three new high-performance grades have been added to the AV grooving line. The new grades include two new chemical vapor deposition (CVD) coated materials, KC9110 and KC9125, which offer performance improvements. The third new grade, KD1405, is a pure diamond-cutting tool material that provides major improvements in tool life on materials such as aluminum alloys with moderate to high-silicon content. The new inch line includes 0.125, 0.187, 0.250, 0.312, and 0.375-in. inserts. Grade KC9110 is an ISO-class P10 grade designed for finishing operations while Grade KC9125 is a P25 class grade designed for universal machining on all types of steel. The key to performance gains offered by these grades are because of advancements in bonding technology that apply three main layers and several additional sublayers of coating with a total thickness of 18 microns. These coatings are 25 to 75 percent thicker than conventional coated carbides. KD1405 results from a breakthrough in diamond processing technology that achieves higher strength and toughness without a binder, resulting in improvements to wear-resistance.
