Sandvik Coromant 5727963 Boring Bar Reducing Adapter

Product Description

The SANDVIK COROMANT 5727963 is a boring bar reducing adapter in the Coromant Capto series, designed to allow technicians to mount smaller-shank boring bars into larger-bore toolholders on CNC turning centers and machining centers. The adapter reduces the effective bore diameter of the tool interface, enabling shops to maximize existing tooling investments without purchasing additional dedicated holders. It ships as a single unit and is suited for professional machining environments where toolholder compatibility and rigidity at the spindle interface are critical to achieving consistent bore tolerances.

This reducing adapter is used in metal-cutting applications on CNC lathes, turning centers, and milling machines equipped with Coromant Capto tooling systems. It is typically installed by machining technicians and tool-room personnel during setup when a smaller boring bar must be adapted to a larger Capto interface. The adapter supports operations in both production and job-shop environments where toolholder interchangeability and quick changeover are priorities.

Key Features

• Coromant Capto series interface for high rigidity and repeatability at the spindle connection
• Reduces bore interface size to accept smaller-shank boring bars without a dedicated holder
• Single-unit package quantity for straightforward procurement and inventory control
• Weighs 1.55 pounds, indicating a solid, full-metal construction appropriate for dynamic cutting loads

Compatibility

Designed for use with Coromant Capto series tooling systems. Consult SANDVIK COROMANT toolholder selection documentation to confirm specific shank size compatibility before installation, as no additional model-specific fitment data was provided.

Installation Notes

Installation should be performed by a qualified machining technician or tool-room specialist familiar with Coromant Capto interface procedures. Power down and lock out the machine spindle before installing or removing any toolholder adapter. Ensure all mating surfaces are clean and free of chips or burrs before seating the adapter to preserve clamping accuracy and interface rigidity. Follow the machine tool manufacturer and SANDVIK COROMANT torque and clamping guidelines as specified in the applicable product documentation.
