The Royal Quick-Change Tool System provides a fast method for changing tools on a Bridgeport-style mill โ once the R8 body is installed in the machine spindle, tools can be changed in seconds
One hand operation โ 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 โ 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
