Rotary Coolant Adapter (RCA)

The Rotary Coolant Adapter (RCA) is a cost-effective system that provides the ability to utilize modern through-coolant cutting tools on machines that do not have through-spindle coolant. CNC machines with automatic tool change and machines with manual clamping systems can both utilize the RCA.

For use with:

T-A drill holders
Structural steel T-A drill holders
Universal drill holders
