Sandvik Coromant 5729324 Boring Bar Modular Adapter C6

Product Description

The SANDVIK COROMANT 5729324 is a boring bar modular adapter designed for use in precision internal turning and boring operations on CNC machining centers and turning centers. This adapter features a 2.4803-inch (63 mm) bore diameter, a 50 mm bore depth, and a C6 connection size, making it suitable for modular tooling setups that require rigid, repeatable clamping. Internal coolant delivery channels direct cutting fluid to the tool tip for improved chip evacuation and thermal management during deep-bore operations. At 3 pounds, the adapter is machined for dimensional accuracy consistent with modular quick-change tooling systems. It is installed by machinists and toolroom technicians working with compatible modular boring bar assemblies.

This adapter is intended for metalworking applications where modular boring bar systems are used in place of solid-shank tooling. Typical installations include CNC lathes, turning centers, and horizontal boring mills running internal diameter operations on steel, cast iron, and similar workpiece materials. The C6 connection size fits modular toolholding systems that use the corresponding interface standard. The lock screw interface is compatible with lock screw part number 3212 010-409. This adapter is appropriate for both production and job-shop environments where tool changes must be fast and positioning must be repeatable.

Key Features

• 2.4803-inch (63 mm) bore diameter for precise internal tooling fitment
• 50 mm bore depth supports deep-reach internal diameter operations
• C6 modular connection size for compatibility with standard quick-change tooling interfaces
• Internal coolant delivery channels improve chip control and extend tool life during bore operations
• Lock screw size of 2.04 inches for secure clamping of the boring bar insert or shank
• Compact body length of 1.9685 inches (50 mm) minimizes overhang in tight-clearance applications

Compatibility

Compatible with modular boring bar systems using a C6 connection interface. Lock screw compatibility confirmed for lock screw part number 3212 010-409. Consult your modular tooling system documentation to confirm full system compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with modular boring bar systems. Before mounting or removing this adapter, confirm the machine spindle is fully stopped, the turret or tool station is in the safe position, and all energy sources are locked out per facility LOTO procedures. Use the specified lock screw and apply torque only with the correct wrench to avoid galling the interface bore. Verify coolant port alignment with the machine coolant supply before clamping the adapter into its final position.
