1/8IN R-8 Quick Change End Mill Holders

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 a the machine spindle, tools can be changed in seconds.
• On 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 run out is less than 0.0005” TIR
• 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.
