Sandvik Coromant 5729100 Boring Bar Reducing Adapter C5

Product Description

The SANDVIK COROMANT 5729100 is a boring bar reducing adapter designed to interface modular tooling systems in CNC turning and boring applications. This adapter steps down the inside connection to a C5 Coromant Capto size, allowing machinists and tooling technicians to use smaller boring bars within a larger tool holding setup. The hole diameter measures 50 millimeters and the overall length is 100 millimeters. Built-in coolant-through capability delivers cutting fluid directly to the cutting zone, supporting extended tool life and chip evacuation in deep-bore operations. This part is installed by toolroom technicians and CNC setup machinists working with modular boring systems.

This reducing adapter is suited for use in CNC lathes, machining centers, and boring mills where modular Coromant Capto tooling is specified. It is commonly installed when a technician needs to adapt a larger Capto interface to a C5 modular connection for smaller diameter boring bar assemblies. The coolant-through design makes it appropriate for deep-hole boring operations where flood coolant at the tool tip is required for thermal management and chip removal. Typical installations are found in production turning cells and job-shop environments running steel, stainless, or cast iron components.

Key Features

• Coromant Capto series modular interface for rigid, repeatable tool connections
• Inside modular connection size C5 for compatibility with C5 boring bar assemblies
• 50 millimeter hole diameter for precise adapter fitment
• 100 millimeter overall length provides reach for standard boring setups
• Coolant-through design channels cutting fluid directly to the cutting zone

Compatibility

Designed for use with Coromant Capto modular tooling systems requiring a C5 inside modular connection. Consult current SANDVIK COROMANT tooling catalogs and assembly charts to confirm fitment with specific boring bar assemblies and machine spindle interfaces before installation.

Installation Notes

Installation should be performed by a qualified toolroom technician or CNC setup machinist. Ensure the machine spindle is fully stopped and all energy sources are locked out before handling or mounting the adapter. Verify that mating Capto interfaces are clean and free of chips or burrs before assembly, as contamination at the taper contact will affect runout and clamping force. Torque all clamping elements per the machine tool or toolholder manufacturer documentation — do not estimate clamping torque.
