I have a woodruff key cutting broach for cutting key slots inside gears pulleys etc. The base is .190 thick and the cutter end .095 on the cutter end. it comes with a custom made guide that is .482" diameter step to .500 and it is about 1-1/8 long. It was only used twice on a specialty application. Free shipping UPS Ground included. Please see my other listings for more Automotive and marine mechanics and machinist tools and parts.
