Seco Tools Australia offers a comprehensive range of Bridge Boring Bars and Jumbo Bridge Bars designed for large diameter boring, overturning and grooving applications. The bridge bar range covers diameters of 204 to 655 mm, whereas the jumbo bridge bars cover the 654 to 2155mm range, and are constructed from high tensile aluminium with steel interfaces.
Both models of bridge boring bars feature a strong design for extra rigidity and power (boring blocks clamped within the Bridge Bar, Bridge Bars clamped within the Jumbo body). They also feature a micrometric screw on the side of the bars for easy access and setting, and an angular orientation every 30 degrees for easy storing in machine magazines.
The bridge bars and jumbo bridge bars offer flexibility in applications, with symmetrical and staggered boring for rough boring capabilities. Large OD overturning is also possible.
