Clearing the waste plug from a hole saw is no longer a problem. Designed for saws with a 5/8" mounting hole, this hole-saw mount has a quick-release button that lets you slide the mount up the shaft to expose the plug for easy removal. The spring-loaded locking pins are retractable for quick blade changes.
For use in a 1/2" chuck, the 7/16" hex-shank comes with a 1/4" high-speed steel pilot bit. A clever product, made in Holland.
