Sandvik Coromant 5728577 Boring Bar Modular Adapter

Product Description

The SANDVIK COROMANT 5728577 is a boring bar modular adapter designed for precision internal turning and boring operations in CNC machining environments. This adapter features a 1.9685-inch bore diameter, a 50mm bore depth, and a C5 connection size, making it suitable for modular tooling systems that demand repeatable positioning and rigid clamping. Internal coolant delivery is built in, directing cutting fluid directly to the cutting zone for improved chip evacuation and tool life. Machinists and tooling technicians working in production or job-shop settings install this adapter as part of a modular boring system. The lock screw interface accepts 3212 010-409 hardware for secure assembly.

This adapter is intended for use in modular boring bar setups where a standardized C5 interface is required. The 1.9685-inch body diameter and 1.9685-inch body length match the bore depth, keeping the assembly compact within the tool overhang envelope. Internal coolant compatibility makes this adapter well suited for deep-bore applications in steel, cast iron, and other materials where heat and chip buildup are concerns. It is typically installed in machining centers and CNC lathes operating with modular quick-change tooling systems.

Key Features

• C5 connection size for compatibility with modular boring bar systems
• 1.9685-inch bore diameter and 50mm bore depth for precise internal turning
• Internal coolant delivery for direct cutting zone cooling and chip control
• Lock screw size of 2.04 inches compatible with 3212 010-409 lock screw hardware

Compatibility

Designed for use with C5 interface modular tooling systems. Lock screw compatibility is confirmed for 3212 010-409 hardware. No additional specific compatible model numbers were provided in product data.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular boring bar systems. Ensure the machine spindle and coolant supply are fully de-energized and depressurized before assembling or disassembling the adapter. Use the specified lock screw hardware and follow the tooling manufacturer torque procedures for the C5 interface. Verify coolant passages are clear and unobstructed before returning the tool to service.
