Sandvik Coromant 5730221 Boring Bar Reducing Adapter

Product Description

The SANDVIK COROMANT 5730221 is a boring bar reducing adapter in the Coromant Capto series, designed to connect boring bars of different shank sizes within a modular tooling setup. This adapter allows machinists and tooling technicians to use smaller-diameter boring bars in larger Capto interfaces, extending the range of an existing tooling inventory without requiring dedicated holders for each bar size. Weighing 8.17 pounds, it is a substantial, precision-machined component built for rigidity in turning and boring operations on CNC lathes and machining centers.

This adapter is suited for production and job-shop environments where modular tooling systems are used on CNC turning centers, mill-turn machines, or boring mills. It fits into the Coromant Capto modular interface, a widely adopted quick-change system in precision machining. Installation is performed by tooling setup technicians or machinists during tool presetting or machine changeover routines.

Key Features

• Coromant Capto series interface for modular quick-change tooling compatibility
• Reducing adapter design allows smaller boring bars to seat in larger Capto connections
• Precision-machined construction supports rigid, accurate boring operations
• Weighs 8.17 pounds, indicating a robust, full-metal build suitable for heavy-duty use
• Single-piece packaging with a minimum order quantity of 1

Compatibility

Designed for use within the Coromant Capto modular tooling system. Specific compatible boring bar shank sizes and Capto coupling sizes were not provided in the available product data. Verify the coupling size and bore diameter against your existing Coromant Capto setup before ordering.

Installation Notes

Installation is performed by a qualified machinist or tooling technician during machine setup or tool changeover. Ensure the machine spindle or turret is fully powered down and the tool carousel is locked before handling or mounting any tooling adapter. Follow the machine tool manufacturer torque guidelines for Capto coupling clamping, and inspect mating surfaces for burrs or contamination before assembly. Consult SANDVIK COROMANT documentation for the specific coupling size to confirm proper fitment.
