Sandvik Coromant 5729438 Boring Bar Reducing Adapter C6

Product Description

The SANDVIK COROMANT 5729438 is a boring bar reducing adapter designed to connect Coromant Capto tooling systems to boring bar assemblies of a smaller size interface. This adapter allows machinists and toolroom technicians to use existing Coromant Capto spindle connections with reduced-shank boring bars, maintaining rigidity and concentricity in the tooling stack. The C6 size designation indicates the Capto coupling size this adapter accepts on the machine side. At 4.99 pounds, it is built for stability in demanding metal-cutting operations including internal diameter boring on CNC lathes and machining centers.

This adapter is suited for production and job-shop environments running Coromant Capto modular tooling where a size reduction in the boring bar interface is required. It is typically installed by CNC machinists or toolroom specialists setting up internal turning or boring operations. The Coromant Capto series is widely used in both horizontal and vertical turning centers as well as multi-task machines where quick-change tooling and precise repeatability are critical to cycle time and part quality.

Key Features

• C6 Coromant Capto interface for direct coupling to compatible machine spindles and tooling blocks
• Reducing adapter design allows use of smaller-shank boring bars within a larger Capto tooling system
• Solid construction supports rigidity and vibration damping during internal boring operations
• Part of the Coromant Capto modular tooling system for flexible, repeatable setup changes
• Weighs 4.99 pounds, indicating robust material cross-section for stable tool overhang

Compatibility

Designed for use within the Coromant Capto modular tooling system at the C6 coupling size. Consult SANDVIK COROMANT tooling documentation to confirm boring bar shank size compatibility on the output side before assembly.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician familiar with Coromant Capto coupling procedures. Ensure the machine spindle and all tooling interfaces are clean and free of debris before assembling the adapter. Power down and lock out the machine before any tooling changes. Follow the torque and clamping procedures specified in the SANDVIK COROMANT Coromant Capto system documentation for the C6 interface.
