Precision CNC Lathe Boring Bar - Premium Micro Carbide Tool for Small Hole Machining

Ultra-fine tungsten carbide tip ensures exceptional durability and precise cutting performance in high-speed operations. Mirror-polished surface reduces friction for smoother internal boring with superior finish quality.

Specialized micro-size design (1-6mm diameter range) tackles intricate small-hole machining tasks in watchmaking, medical devices, and electronics components.

Full CNC-ground geometry maintains consistent cutting angles (±0.1°) for vibration-free operation in hardened materials up to 60HRC.

Interchangeable shank system compatible with most mini-lathes and precision machining centers for versatile workshop applications.

Electroplated cobalt coating enhances heat resistance (withstands 800°C) during continuous dry cutting operations.

Direct-from-factory pricing with bulk order discounts available for industrial users and machining workshops.

Note: Includes protective anti-rust coating with individual vacuum packaging for long-term storage.
