7/64''..Drill bit adaptor - 7/64''
These hexagon shank adapters accept a standard straight shank drill or shaft. They allow you to use your own drills which are held in place by a flat bottom grub screw. They give you the same quick change advantages as the Hexagon Shank drills but with the flexibility of being able to replace the drill should it break. They are designed for timber and in the drill can slip in the holder unless a flat is ground onto the shank of the drill to allow the grub screw more positive contact.
