Sandvik Coromant 5729445 Boring Bar Reducing Adapter C6

Product Description

The SANDVIK COROMANT 5729445 is a boring bar reducing adapter designed for modular tooling systems using the C6 outside modular connection size. This adapter accepts through-coolant delivery, channeling cutting fluid directly to the cutting zone during boring operations. It is used to reduce or adapt between modular interface sizes in a boring bar assembly, allowing shops to extend tooling reach or change interface size without replacing the full tool setup. With an overall length of 4.6457 inches and a weight of 2.92 pounds, this adapter is suited for CNC machining centers and horizontal boring mills where precision internal turning operations are performed. Installation is handled by machinists and tooling technicians.

This reducing adapter is intended for use in modular boring bar assemblies where a C6 outside modular connection is required. Through-coolant capability makes it appropriate for deep bore applications where chip evacuation and heat management are critical. It is well suited for production environments running steel, cast iron, and similar materials where sustained coolant flow to the insert improves tool life and surface finish consistency. The adapter integrates into the modular tooling stack between the spindle-side interface and the boring head or bar extension.

Key Features

• C6 outside modular connection size for compatibility with C6-standard modular tooling systems
• Through-coolant construction routes cutting fluid directly to the cutting zone
• Overall length of 4.6457 inches provides defined reach within the tooling stack
• Solid construction at 2.92 pounds supports rigidity during interrupted and continuous boring cuts
• Reducing adapter function allows interface size changes within an existing modular boring bar setup

Compatibility

Designed for use in modular boring bar assemblies requiring a C6 outside modular connection interface with through-coolant capability. Specific compatible tooling combinations were not provided in the product data; verify interface sizing and coolant port alignment against your existing modular system configuration before installation.

Installation Notes

Installation of this adapter should be performed by a qualified machinist or tooling technician familiar with modular boring bar systems. Disengage machine power and release spindle pressure before assembling or disassembling modular tooling components. Ensure all mating surfaces are clean and free of chips or debris before torquing the modular connection to the tool manufacturer specification. Verify through-coolant port alignment with the adjacent tooling components before running coolant flow.
