Step Boring Bars with Triangle-Shaped Insert

Our step boring bars with triangular inserts are engineered for precise multi-diameter boring in tight spaces. Premium micrograin carbide bodies paired with heat-treated steel heads provide the rigidity and clearance you need, delivering clean chip evacuation and repeatable results.

Designed to hold triangular inserts, these bars are available with optional coolant-through capability and are compatible with flat-top or chipbreaker-style inserts. Each bar includes one insert screw and one insert key. Inserts are sold separately. Whether you are boring, facing, or profiling multiple diameters in one setup, SCT step boring bars are built to perform.
