Quick-Change Tool Holders for Milling Machines
After installing the R8 body in the milling machine spindle, tool holders can be switched out in seconds. To remove a tool holder, depress the brass locking button and rotate the collar on the R8 body. When a new tool holder is inserted, a spring-loaded pin snaps the collar back into the locked position.
