Precision Left-Hand Carbide Boring Bar for Micro Machining
High-performance carbide cutter with ultra-fine grain structure ensures extended tool life and superior edge retention. Perfectly balanced left-hand design enables smooth chip evacuation in confined spaces, ideal for intricate lathe work or fine detail engraving.
Mirror-polished cutting edge reduces friction by 40% compared to standard tools, delivering glass-smooth finishes on brass, aluminum, and soft steels. Ground to ±0.01mm tolerance for vibration-free operation at high RPMs.
Essential for watchmakers, model engineers, and CNC operators requiring precision boring in clockwise-rotation setups. Includes micro-grooves along shank for secure collet gripping. Ships factory-sharpened with anti-oxidation coating.
