These Frame/Joist drills are manufactured from High Speed steel, and have a 118 deg angled tip. The drill bit end is screwed and bonded to shaft thus reducing the risk of breakage and giving better concentricity. The design of the drill helps to reduce the risk of jamming in green wood, and can be used in most electric drills with a 13mm chuck. The drills are ideal for drilling in composite materials with steel or aluminium, profiles, shuttering, hard- and softwoods, lightweight boards and plasterboard.
