Seco Boring Bridges Optimize Deep-Hole Operations

Seco Tools’ BB732 boring bridge is a modular solution designed for deep boring operations with Steadyline
bars. Engineered for both roughing and finishing tasks, BB732 bridges can provide vibration-free performance, optimal coolant flow and high-quality surface finishes.

The BB732 boring bridges are tailored for use with the Steadyline SM40 shell mill holder, supporting
diameters from 114-301 mm for roughing and up to 315 mm for finishing. The conical-reinforced shape of the holder provides high static and dynamic rigidity, while the Steadyline vibration damping system enables stable, high-precision machining even in demanding conditions.

The BB732 bridges eliminate the need for separate tools for roughing and finishing, reducing inventory and setup time. With a built-in safety stopper to prevent block ejection due to centrifugal force, the system also supports operator safety.

“The BB732 boring bridges are designed to work seamlessly with Steadyline bars, especially the SM40 series, for deep boring jobs with larger diameter bars,” says Kavita Dandge, global product manager of machine solutions. “One of the standout features is the optimized coolant flow – it’s directed right at the cutting edge to help break up chips and keep the insert cooler.”
