G39 Valve Guide Fitting Tool

This tool is scientifically shaped, drilled and tapped to hold valve guides and stars for valve instruments. To use, you screw the G39B valve guide into the fitting tool and file it to the proper width to fit the guide slot. When the guide is fitted, remove it from the tool and install it in the valve, then file it to the proper height. The tapered end screws into stars. Saves time and eliminates filing of the valve.
