Indexable Bars

These SCT indexable boring bars are engineered specifically to fit ATD-style triangle inserts, with options available in both 1/4" and 5/16" right-hand configurations. Choose from solid-body bars for general-purpose internal boring or coolant-through styles for enhanced chip evacuation and heat control. Each bar features a durable heat-treated steel head paired with a micro-grain carbide shank for maximum rigidity and long tool life. All bars come equipped with an AT6+ screw and matching flag key for secure insert clamping and easy indexing. ATD inserts are sold separately.
