Sandvik Coromant 5729889 Boring Bar Reducing Adapter C6

Product Description

The SANDVIK COROMANT 5729889 is a boring bar reducing adapter designed to transition between modular tooling interfaces in CNC boring applications. Built around a C6 outside modular connection, this adapter allows machinists and tooling technicians to configure boring bar assemblies that require a reduced interface size. The through-coolant design delivers cutting fluid directly to the tool tip, improving chip evacuation and extending insert life in deep-bore operations. At 5.83 inches overall length and 4.92 pounds, this is a robust, production-grade component intended for use in machining centers and CNC turning or milling environments.

This adapter is suited for shops running modular tooling systems that require interface reduction for tight-clearance or extended-reach boring operations. It fits into existing C6-connection tooling assemblies and is appropriate for both production machining environments and tool crib configurations where modular flexibility is essential. Tooling engineers and setup technicians working with multi-component boring bar assemblies will find this adapter a direct fit for reconfiguring reach or shank size within a modular stack.

Key Features

• C6 outside modular connection for compatibility with standard C6 tooling interfaces
• Through-coolant capability for improved chip evacuation and tool life in deep-bore applications
• Overall length of 5.83 inches suits extended-reach and clearance-sensitive setups
• Solid construction at 4.92 pounds provides rigidity and damping in modular boring assemblies
• Modular design allows quick reconfiguration of boring bar assemblies without full tool replacement

Compatibility

Designed as an OEM-style modular component for use in C6-interface boring bar assemblies on CNC machining centers and turning centers equipped with modular tooling systems.

Installation Notes

Installation should be performed by a qualified tooling technician or machinist. Ensure the machine spindle is fully stopped and all power is off before assembling or disassembling modular tooling components. Clean all mating surfaces and confirm through-coolant ports are clear and properly aligned before torquing the connection. Follow the machine and tooling system manufacturer guidelines for interface torque and assembly procedures.
