Sandvik Coromant 5727987 Boring Bar Reducing Adapter

Product Description

The SANDVIK COROMANT 5727987 is a boring bar reducing adapter in the Coromant Capto series, designed to adapt between differing interface sizes in precision boring applications. Reducing adapters of this type allow machinists and tooling setups to mount smaller-shank boring bars into larger-size Capto spindle connections, maintaining rigidity and concentricity during internal diameter machining. This adapter weighs 0.85 pounds and is sold as a single unit. It is intended for use in CNC turning centers and machining cells where Coromant Capto tooling is the standard interface.

This reducing adapter is suited for shop environments running Coromant Capto modular tooling systems on CNC lathes and turning centers. It is typically installed by machinists or tooling specialists setting up boring operations that require a step-down connection between the machine spindle interface and a smaller boring bar shank. Its role is to extend tooling flexibility without sacrificing the clamping integrity that Coromant Capto coupling is known for.

Key Features

• Coromant Capto series interface for modular tooling compatibility
• Reducing adapter design bridges differing shank sizes in boring setups
• Compact and rigid construction supports internal diameter boring operations
• Sold as a single unit with a package quantity of one

Compatibility

Designed for use within the Coromant Capto modular tooling system on CNC turning centers and machining cells that use Capto-style spindle connections.

Installation Notes

Installation should be performed by a qualified machinist or tooling specialist familiar with Coromant Capto coupling procedures. Ensure the machine spindle is powered down and the turret or tool station is fully secured before mounting or removing the adapter. Follow the tooling manufacturer guidelines for clamping torque and interface cleanliness to maintain concentricity and runout specifications. Inspect the mating surfaces for contamination or damage before assembly.
