Sandvik Coromant 5729828 Boring Bar Modular Adapter C8

Product Description

The SANDVIK COROMANT 5729828 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC lathes and machining centers. It accepts an 80.00 mm (3.1496 inch) bore diameter with a 140.00 mm (5.5118 inch) bore depth, making it suitable for deeper internal machining applications where rigidity and concentricity are critical. The adapter uses a C8 modular connection size and incorporates an internal coolant delivery system to direct cutting fluid directly to the tool tip, improving chip evacuation and extending insert life. Installation is performed by qualified machining professionals in production or job-shop environments.

This modular adapter is intended for use in screw thread lock tooling systems on CNC turning centers and boring mills. The C8 connection interfaces with compatible Sandvik Coromant modular tooling components. Internal coolant delivery is enabled via a compatible coolant screw. The body diameter matches the bore diameter at 80.00 mm (3.1496 inches), and the overall body length is 140.00 mm (5.5118 inches), providing stable support for extended reach boring operations in both production and precision machining environments.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular CNC tooling systems. The machine spindle must be powered down and locked out before mounting or removing any modular adapter. Use the specified lock screw and coolant screw components to ensure proper clamping force and sealed coolant delivery. Do not exceed the machine interface torque specifications outlined in the machine tool manufacturer documentation.
