HOUSTON -- Newkut Industries, a start-up diamond synthesis company, announces the availability of two new grades of Polycrystalline Diamond Compact (PDC) cutter inserts.

Newkut's Zafonic PDC cutter inserts are designed to maximize the hardness and wear resistance of the cutter edge.

"Zafonic PDC cutters feature a proprietary non-planar interface design to effectively distribute residual stress in the cutter layer and thereby ensure that the critical regions of the cutter have been exposed to a favorable stress state," says Matthew Cook, director of International Operations.

Newkut also introduces the Tenzing range with a very high resistance to cutter edge chip, fracture or spalling. Both cutter grades are available in 13, 16 and 19 mm standard diameter and lengths to suit most commonly used cutter sizes.

The performance of Newkut fixed PDC cutters can also be modified to meet particular application requirements, says Cook.
