Sandvik Coromant 5729465 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5729465 is a boring bar modular adapter designed to connect boring bar assemblies within modular tooling systems. It features a 0.75 inch bore diameter, a C6 connection size, and integrated internal coolant delivery to direct cutting fluid precisely at the tool tip. The adapter body measures 2.4803 inches in diameter and 2.6575 inches in body length, with a bore depth of 2.6575 inches. A lock screw secures the boring bar insert or extension in place during machining operations. This component is installed by machinists and tooling technicians in CNC turning, boring, and machining center applications where modular quick-change tooling is used.

This adapter is suited for precision internal boring operations in both production and job-shop environments. It fits into C6-interface modular tooling systems and is typically used in horizontal and vertical machining centers and CNC lathes requiring consistent, repeatable boring bar positioning. The internal coolant feature supports high-speed or deep-bore applications where heat management and chip evacuation are critical. The lock screw size of 2.76 inches is compatible with lock screw part number 5757320 as specified by the manufacturer.
