Rani Tool Corp. offers German-made PCD inserts with CB3 chipbreakers from Becker Diamond Tools. The chipbreaker has a semiserrated wave profile on the flanks of the cutting point, which increases the material-removal rate and produces short, controlled chips. The inserts are suitable for machining with flood coolant or minimal-quantity lubrication.
