Sandvik Coromant 5729317 Boring Bar Modular Adapter C6

Product Description

The SANDVIK COROMANT 5729317 is a boring bar modular adapter designed for precision machining applications requiring a stable, repeatable tooling interface. With a bore diameter of 2.4803 inches (63 mm) and a bore depth of 1.6929 inches (43 mm), this adapter accepts modular boring bar heads and provides a rigid connection between the spindle and cutting unit. It features a C6 connection size, an integrated internal coolant path to direct fluid directly to the cutting zone, and a lock screw interface compatible with the 3212 010-409 screw. Machinists and CNC operators in production and job-shop environments rely on this type of adapter for consistent tool runout and repeatable setup on boring operations.

This adapter is suited for use on CNC lathes, turning centers, and machining cells where the C6 modular tooling interface is specified. It is used in both roughing and finishing boring operations on ferrous and non-ferrous workpieces. The internal coolant design makes it appropriate for deep-bore passes and hard-material applications where heat and chip evacuation are critical. The body diameter matches the bore diameter at 2.4803 inches (63 mm), and the body length is 1.6929 inches (43 mm), making it a compact adapter suited for applications with limited overhang.

Key Features

• C6 modular connection size for compatibility with C6-series tooling systems
• Bore diameter of 2.4803 inches (63 mm) with matching body diameter
• Bore depth of 1.6929 inches (43 mm) for stable head seating
• Internal coolant path directs fluid to the cutting zone for improved tool life and chip control
• Lock screw interface compatible with lock screw 3212 010-409
• Compact body length of 1.6929 inches (43 mm) minimizes overhang

Compatibility

Designed for use with C6-series modular boring bar systems. Lock screw compatibility is specified for part number 3212 010-409. Refer to the SANDVIK COROMANT C6 tooling system documentation to confirm head and holder compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician familiar with modular tooling systems. Power down and lock out the machine spindle before mounting or removing any tooling adapter. Use the specified lock screw and follow the tooling manufacturer torque sequence for the connection interface. Verify internal coolant passages are clear and properly aligned before engaging the coolant system.
