So if you want to use your K&M mandrels in one of our neck turning tools or maybe you want to use one or those K&M mandrels in your Sinclair Neck turning tool, this little sleeve does just that.

Simply drop the sleeve into your neck tool where the 3/8" shank mandrel goes, thread the mandrel locking screw into the through hole in the sleeve and install your K&M mandrel in the neck tool as normal.
