Sandvik Coromant 5729511 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5729511 is a boring bar modular adapter designed for precision internal turning and boring operations on CNC machining centers. It features a 0.375-inch bore diameter, a bore depth of 65 millimeters (2.5591 inches), and an internal coolant design that directs cutting fluid directly to the cutting zone. The C6 connection size provides a secure, repeatable interface between the machine spindle and the boring bar assembly. Weighing 2.56 pounds, this adapter is built for production environments where dimensional accuracy and thermal control during deep-bore operations are critical. Machinists and tooling specialists working with modular tooling systems are the primary installers of this component.

This modular adapter is suited for internal boring applications on lathes and turning centers equipped with a C6 modular interface. The body diameter measures 63 millimeters (2.4803 inches) and the body length is 65 millimeters (2.5591 inches), making it appropriate for medium-depth bores in both ferrous and non-ferrous workpiece materials. Internal coolant capability supports high-speed cutting strategies and helps extend tool life in demanding production cycles. The adapter is compatible with lock screw part number 5757318 for secure assembly.

Compatibility

Compatible with C6 modular tooling interfaces. Lock screw compatibility confirmed for part number 5757318. Designed as an OEM-style modular adapter replacement for systems using the C6-131-00065-375 designation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular boring bar systems. Disengage machine power and lock out the spindle before assembling or disassembling the adapter. Ensure all mating surfaces are clean and free of chips or debris before assembly to maintain concentricity and prevent interface damage. Verify internal coolant passages are clear and properly aligned before returning the machine to service.
