Sandvik Coromant 5729443 Boring Bar Reducing Adapter C6

Product Description

The SANDVIK COROMANT 5729443 is a boring bar reducing adapter with a C6 outside modular connection size and integrated through-coolant capability. This adapter is used to reduce the interface between a larger modular toolholder and a smaller boring bar shank, maintaining coolant flow directly to the cutting zone throughout the connection. At 3.0709 inches in overall length and 2.17 pounds, it is a compact, solid component built for precision boring operations in metal-cutting environments. It is installed and serviced by machinists and toolroom technicians working with modular tooling systems on CNC lathes and boring machines.

This adapter is suited for shops running modular tooling setups where boring bar shank sizes must be matched to larger turret or block interfaces. The C6 modular connection follows the Coromant Capto interface standard, making it appropriate for use in high-precision turning centers and machining cells where repeatable tool positioning and through-coolant delivery are required. It is a practical component for production environments performing internal diameter boring on ferrous and non-ferrous workpieces.

Key Features

• C6 outside modular connection size for compatibility with C6-interface toolholding systems
• Through-coolant design directs coolant to the cutting edge for improved chip evacuation and tool life
• Overall length of 3.0709 inches supports close-clearance boring applications
• Compact 2.17-pound construction balances rigidity with reduced overhang mass
• Modular adapter design allows quick boring bar changes without disturbing the main toolholder

Compatibility

Designed for use with C6 modular toolholder interfaces in Coromant Capto-compatible turning centers and boring machines. No additional specific model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with modular tooling systems. Ensure the machine spindle or turret is fully stopped and all hydraulic or pneumatic clamping pressure is relieved before disassembling or installing modular connections. Verify that mating C6 surfaces are clean and free of chips or burrs before assembly to maintain accurate tool positioning. Consult the machine tool and toolholder manufacturer documentation for torque and clamping procedures specific to the C6 interface.
