Royal R8 Quick-Change Tool System
- The Royal Quick-Change Tool System provides a fast method for changing tools on a Bridgeport-style mill – once the R8 body is installed in the machine spindle, tools can be changed in seconds.
- One hand operation – simply depress the brass locking button and rotate collar to the locked-open position. When a new tool is inserted, it depresses a spring-loaded pin, snapping the collar back into the locked-closed position.
- Very accurate – total system runout can be less than 0.0005" TIR under the right circumstances.
- Short overhang (1 1⁄8") and two positive-drive keys enable many common milling and drilling operations to be easily performed.
Please note that this tool is designed for light/medium-duty applications where the ability to change tools quickly outweighs the need for extreme rigidity. We do not recommend using this system for heavy milling or high-production applications.
Endmill Tool Holder:
- Single endmills only. Designed for minimum overhang.
