BORING BAR HOLDER

Internal,External coolant supply

Engineered for high-performance CNC turning centers, this Boring Bar Holder delivers exceptional rigidity and repeatable positioning accuracy for both internal and external boring operations. Designed to Miyano system tooling standards, it ensures seamless compatibility with major CNC lathe turrets. The holder supports both internal and external coolant supply, directing cutting fluid precisely to the tool tip to reduce thermal deformation, extend insert life, and maintain tight tolerances during deep-bore machining. The precision-ground shank and hardened steel body minimize vibration and tool deflection, making it suitable for high-speed, high-feed applications on difficult-to-cut materials including stainless steel, titanium, and hardened alloys. Key technical features include a robust clamping mechanism for fast, tool-free bar changes, micron-level runout control, and high torque resistance under interrupted cuts. The compact form factor allows use in tight-clearance turret configurations without sacrificing stability. Ideal for automotive components, hydraulic valve bodies, medical implants, and precision aerospace parts where bore geometry and surface finish are critical.
