Sandvik Coromant 5728216 Boring Bar Modular Adapter C4

Product Description

The SANDVIK COROMANT 5728216 is a boring bar modular adapter designed to connect modular boring systems in precision machining applications. It features a 0.9055-inch (23.00 mm) bore diameter and a C4 connection size, making it compatible with C4-standard modular tooling interfaces. The adapter has a body diameter of 0.7874 inches (20.00 mm) and an overall length of 4.1929 inches (106.50 mm). Internal coolant delivery is supported, directing cutting fluid directly to the cutting zone for improved chip evacuation and tool life. This adapter is installed by machinists and tooling specialists in CNC turning and boring operations requiring modular, quick-change tooling setups.

This adapter fits into modular boring and turning setups on CNC lathes and machining centers where C4-interface tooling is used. It is suited for both production and job-shop environments where repeatable tool change accuracy is required. The internal coolant path makes it well-suited for deep-bore operations and difficult-to-machine materials where heat management at the cutting edge is critical. The body length of 1.2008 inches (30.50 mm) provides a compact coupling profile that minimizes overhang while maintaining rigidity.

Compatibility

Designed for use with C4-interface modular boring and turning tooling systems. Specific compatible heads, shanks, or machine models were not identified in the available product data; verify C4 interface compatibility with your existing tooling setup before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling specialist familiar with modular boring system assembly. Power down and lock out the machine spindle before mounting or removing any tooling adapter. Ensure all mating surfaces are clean and free of chips or burrs before assembly to maintain interface accuracy. Verify coolant port alignment when connecting internal coolant supply lines to avoid flow restriction.
