Sandvik Coromant 5728469 Boring Bar Modular Adapter C5

Product Description

The SANDVIK COROMANT 5728469 is a boring bar modular adapter designed for precision internal boring operations in CNC machining environments. With a 1.9685-inch bore diameter and a C5 connection size, this adapter interfaces between the machine spindle and a compatible boring bar to extend reach and maintain rigidity. The body measures 5.1378 inches in length with a bore depth of 1.4370 inches, supporting stable tool engagement in tight-tolerance bores. External coolant delivery keeps cutting zones clear during extended cuts. This adapter is installed by machinists and tool-room technicians working with modular tooling systems.

This adapter suits horizontal and vertical machining centers running modular boring systems that accept C5 interface connections. It is well-suited for medium to large-bore applications in production and job-shop environments where modular tooling flexibility and quick changeover are priorities. The external coolant configuration makes it a practical choice for materials that generate significant heat at the cutting zone. A compatible lock screw, part number 5758460, is used to secure the boring bar within the adapter.

• External coolant design directs fluid to the cutting area during operation
• Screw thread lock mechanism with compatible lock screw 5758460
• Body diameter of 1.9685 inches matches bore diameter for a uniform profile

Compatibility

Designed for use with C5-connection modular boring systems. Compatible lock screw part number is 5758460. Manufacturer cross-reference part number C5-RC2085-32130-20M is associated with this adapter.

Installation Notes

Installation should be performed by qualified machinists or tooling technicians with the machine powered down and spindle motion fully stopped before handling the adapter. Verify that the C5 interface surfaces are clean and free of chips or burrs before seating the adapter. Use the designated lock screw (5758460) to secure the boring bar; do not substitute fasteners. Follow the machine tool manufacturer guidelines for torque and runout verification after assembly.
