The Vajra® Standard Inserts series is part of the “VAJRA” ultra-precision machining tool portfolio from JD Diamond Tool. According to the manufacturer: • “Vajra® Standard inserts … breakthrough MCD material processing space, development diversified ‘Vajra’ series MCD ultra-precision machining tool series, widely used in precision turning, milling, drilling, and nano-scale high polishing surface machining.” • The term “MCD” here stands for monocrystalline diamond (or synthetic single-crystal diamond) material, which offers very high hardness, excellent wear resistance, low friction, high thermal conductivity and low thermal expansion — important for ultra‐precision machining of non-ferrous or difficult-to-machine materials. • The Vajra® Standard Inserts appear to be a “standard blade/ECO” component category under the product mix. Thus, the series is positioned for high-precision finishing, ultra-fine geometry, and minimal variation in critical surfaces, likely in non-ferrous, composite or high-end manufacturing environments. In simpler terms: these inserts are cutting-tool inserts made from (or tipped with) ultra-hard diamond material (MCD) designed for very precise turning, milling or drilling operations where surface finish, tool life and dimensional accuracy are premium.
