Precision MQR Tool Bar for Micro Boring & Fine Finishing

Ultra-fine stainless steel shank ensures vibration-free operation in high-speed machining. Tungsten steel cutting head with micro-grain structure delivers exceptional wear resistance for prolonged tool life.

Specialized for small-diameter inner hole machining (0.5-3mm) in watch components, medical instruments, and precision hydraulic systems. Mirror-finish alloy forming capability eliminates secondary polishing.

Heat-treated alloy core maintains rigidity during deep-hole boring while reducing material adhesion. Compatible with CNC lathes and Swiss-type automatic machines for mass production environments.

Full-surface anti-corrosion coating prevents coolant erosion in wet machining conditions. Ground within 0.001mm tolerance for concentricity-critical aerospace applications.

Customizable shank lengths (50-150mm) available for batch orders. ISO9001-certified manufacturing with lifetime technical support for bulk procurement clients.
