That is why the FEIN Starlock power tool and the accessory system works faster, more conveniently and more economically than previous systems with conventional tool mounts. The accessory is pushed onto the power tool mount and locks in securely, without play. The tool change takes less than three seconds. FEIN Starlock accessories are equipped with a recessed, three-dimensional mount and achieves more precise results and up to 45% faster work progress.
