Sandvik Coromant 5729359 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5729359 is a boring bar modular adapter designed for precision internal turning and boring applications in CNC machining environments. It features a 1.5-inch bore diameter, an 85 mm bore depth (3.35 inches), and a C8 connection size with a body diameter of 3.15 inches. Internal coolant delivery is integrated into the design, directing cutting fluid directly to the cutting zone for improved chip evacuation and tool life. This adapter is installed by machinists and tooling technicians on modular boring bar systems used in production and job shop settings. It weighs 6.01 pounds.

This modular adapter is suited for internal boring operations on medium to large machining centers and turning centers equipped with compatible modular tooling interfaces. The C8 connection size positions it for use in applications requiring rigid, repeatable tool changes with consistent axial and radial runout. Internal coolant capability makes it well suited for deep bore applications where flood coolant is ineffective. The lock screw interface is compatible with lock screw part number 5763355.

Key Features

• 1.5-inch bore diameter for accurate tool positioning in internal turning setups
• 85 mm (3.35-inch) bore depth supports extended reach boring operations
• C8 modular connection size for rigid, repeatable tool assembly
• Internal coolant delivery directs fluid to the cutting zone for improved chip control and tool life
• 3.15-inch body diameter provides stable support in the toolholder
• Compatible with lock screw 5763355 for secure screw thread locking

Compatibility

Compatible with C8 modular boring bar systems. Lock screw compatibility confirmed with part number 5763355. Consult the SANDVIK COROMANT Coromant Capto or modular tooling system documentation to verify fitment with your specific machine interface before installation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with modular boring bar systems. Power down and lock out the machine spindle before assembling or disassembling the adapter. Ensure the mating surfaces of the C8 connection are clean and free of chips or debris before torquing the lock screw. Verify internal coolant port alignment with the machine coolant supply before initiating a cutting program.
