Single-angle Polycrystalline Diamond (PCD) standard inserts are precision cutting tools engineered for non-ferrous metals, composites, and abrasive non-metallic materials such as aluminum alloys, copper, brass, magnesium, carbon-fiber-reinforced plastics (CFRP), and ceramics. The insert features one fixed relief angle (for example 7°, 11°, or as specified) that provides stable cutting geometry, excellent chip evacuation, and a consistent surface finish during high-speed turning, boring, or milling operations.

A PCD polishing tool is a machining/polishing instrument whose active surface is made of or tipped with PCD (polycrystalline diamond) material, designed to deliver very high-quality surface finishes (including mirror or near-mirror finishes) on workpieces. For example, one supplier describes a PCD polishing tool “dedicated to mirror polishing, and roughness is below Ra 0.03.” These tools are used in ultra-precision finishing operations, often on non-ferrous metals, composites, plastics, optical surfaces, moulds, etc. Because PCD is extremely hard, wear-resistant and can maintain geometry, these polishing tools can reduce manual labor, improve consistency, and extend service life compared to conventional polishing/finishing tools.

Integral PCBN (Polycrystalline Cubic Boron Nitride) standard inserts are one-piece solid PCBN cutting tools—the entire insert is made from PCBN rather than having only a brazed PCBN tip. This monolithic design delivers maximum hardness and thermal stability for continuous or interrupted machining of hardened steels, chilled cast iron, powder metals, and other wear-resistant alloys. Because there is no carbide substrate, the insert offers uniform PCBN properties throughout, making it ideal for aggressive cutting conditions, long production runs, and tight tolerance finishing.
