Sandvik Coromant 5729329 Boring Bar Modular Adapter C6

Product Description

The SANDVIK COROMANT 5729329 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC machining centers and lathes. This adapter accepts boring bars with a 1.2598-inch (32.00 mm) bore diameter and provides a bore depth of 1.5157 inches (38.50 mm). It features an internal coolant channel, delivering coolant directly to the cutting zone for improved chip evacuation and tool life in demanding materials. With a body diameter of 2.4803 inches (63.00 mm) and a C6 modular connection, the adapter integrates cleanly into compatible tooling systems. Weighing 2.25 pounds, it is built for stable, repeatable performance in production environments. Machinists and tooling setters install this adapter as part of a modular boring system.

This modular adapter is suited for internal boring applications in both production and job-shop environments. The C6 connection size supports integration into modular tooling platforms commonly used on multi-axis CNC machining centers and turning centers. Internal coolant delivery makes it well suited for deep-bore applications or work in materials prone to heat buildup. The lock screw size of 1.5700 inches is compatible with lock screw part 3212 010-308. This adapter is installed by machinists and CNC tooling technicians in shops requiring consistent, repeatable boring setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician familiar with modular boring systems. Power down and lock out the machine spindle before installing or removing the adapter. Ensure all mating surfaces are clean and free of chips or burrs before assembly to maintain concentricity and clamping integrity. Verify coolant port alignment when connecting to the machine coolant supply to ensure unobstructed internal coolant flow.
