Sandvik Coromant 5729094 Boring Bar Reducing Adapter

Product Description

The SANDVIK COROMANT 5729094 is a boring bar reducing adapter designed to interface modular tooling systems with smaller-shank boring bars. This adapter belongs to the Coromant Capto series, a modular quick-change coupling platform widely used in CNC turning, boring, and machining centers. It allows shops to adapt existing Coromant Capto spindle connections to a reduced bore diameter, extending the usability of current tooling inventory without requiring a full tool change. Installation is handled by machinists and CNC tooling technicians as part of a standard tooling setup procedure. The adapter weighs 1.62 pounds.

This reducing adapter is suited for production machining environments where modular tooling flexibility is required. It fits into setups on CNC lathes, turning centers, and machining centers that use the Coromant Capto quick-change system. Typical applications include internal boring operations where the machine spindle interface is larger than the boring bar shank being used, making a reducing adapter necessary to maintain rigidity and concentricity through the tooling stack.

Key Features

• Coromant Capto series modular coupling for quick-change tooling compatibility
• Reduces spindle interface to smaller boring bar shank diameter
• Supports rigid, concentric tooling connections in internal boring operations
• Compact and durable construction at 1.62 pounds
• Package quantity of 1 adapter per unit

Compatibility

Designed as an OEM-style replacement and modular tooling component for CNC turning and boring setups using the Coromant Capto quick-change coupling system.

Installation Notes

Installation of this adapter should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before mounting or removing any tooling components. Follow the machine tool manufacturer torque and clamping guidelines for the Coromant Capto interface as specified in your machine documentation. Verify concentricity and runout after assembly before returning the machine to operation.
