Achieve high concentricity and maximum rigidity during heavy internal boring, profiling, and threading operations with industrial-grade Boring Bar Holders (CNC lathe block holders). Precision-engineered with ground locating faces and a heavy-duty cylindrical clamping bore, these tool blocks securely seat round-shank boring bars. Outfitted with multiple top set screws and integrated internal coolant delivery ports, they provide uniform 360-degree radial locking force and targeted coolant flow to the cutting edge, suppressing chatter and extending tool insert life during deep internal turning cycles.
