BORING BAR: C25S–STUPR11 25.0MM ANTI-VIBRATION

Anti-vibration boring bars use internal dampening mechanisms—typically a heavy metal mass (like tungsten) suspended in rubber or oil—to absorb chatter, allowing for deep cutting, often 7x to 14x the tool diameter.
* The process involves using high-positive rake inserts to reduce cutting forces, applying internal coolant, and securing the bar using a full-round clamping method
