The Vajra® Chamfer Tools are part of a premium “Vajra®” series of ultra-precision cutting tools developed by JD Diamond Tool Precision Manufacturing Co., Ltd. (JD Diamond Tool) for high-accuracy machining operations. The catalogue mentions “Vajra® Chamfer tools … widely used in precision turning, milling, drilling, and nanoscale high polishing surface machining.” These tools are designed for chamfering operations — i.e., creating a bevel or angle on an edge or hole (commonly 15°, 30°, 45°, etc) to remove burrs, improve aesthetics, facilitate assembly/welding, or improve stress distribution at edges. Because they belong to the ultra-precision “Vajra®” series, these chamfer tools emphasise extremely high accuracy, advanced materials (such as monocrystalline diamond or ultra-hard tool grades), minimal tool wear, and excellent surface finish.

The PCD Standard Insert WB Type (Hexagon, 5° Clearance Angle) is a precision cutting insert designed for high-speed turning, facing, and profiling of non-ferrous and abrasive materials. Its polycrystalline diamond (PCD) cutting edge delivers exceptional wear resistance, while the hexagonal shape offers multiple cutting edges, reducing tooling cost per part.

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.
