Designed with the woodturner in mind, the beefy 3/8" shaft of this mandrel will easily fit into any collet, keyed or keyless chuck. Another benefit is the cutting action of the double tapping flutes that assist in cutting threads easily into your turning stock. Removal of the turning stock will become much easier than ever before, and installation of the stopper will be a snap. Use this mandrel to create bottle stoppers, badger hair bristle brushes and many other small turnings. Simply drill a 7/32" hole in your wooden blank, thread onto the mandrel, and turn your favorite shape.
