Sandvik Coromant 5727961 Boring Bar Reducing Adapter

Product Description

The SANDVIK COROMANT 5727961 is a boring bar reducing adapter in the Coromant Capto series, designed to interface between a machine spindle and a smaller-shank boring bar. Reducing adapters of this type allow machinists and tooling technicians to mount a boring bar with a reduced coupling diameter into a larger Capto spindle without swapping the full toolholder assembly. At 1.25 pounds, the adapter is sized for practical bench or turret use. It is installed by qualified tooling or machining professionals in CNC turning, boring mill, and machining center applications.

This adapter suits shops running Coromant Capto-compatible spindles that require a step-down interface for smaller-diameter boring bars. It is appropriate for both production and job-shop environments where toolholder flexibility across varying bore diameters is required. The Coromant Capto system is a common modular tooling standard found in CNC lathes, turning centers, and multi-task machines.

Key Features

• Coromant Capto series interface for modular tooling compatibility
• Reduces coupling diameter to accept smaller boring bars without full spindle changeout
• Compact, rigid design supports accurate boring operations
• Weighs 1.25 pounds for manageable handling and installation

Compatibility

Designed as a modular reducing adapter for use with Coromant Capto series tooling systems. Consult SANDVIK COROMANT tooling documentation to confirm specific coupling size compatibility before installation.

Installation Notes

Installation should be performed by a qualified tooling technician or machinist. Power down and lock out the machine spindle fully before mounting or removing any toolholder adapter. Follow the machine tool manufacturer torque guidelines for Capto coupling draw bolts, using the appropriate Capto assembly tools. Inspect mating surfaces for contamination or damage before assembly to ensure proper seating and runout performance.
