This drill and driver bit kit will suit all leading brands of pocket hole jigs. The kit consists of a titanium coated stepped drill bit, a locking depth stop collar and a square pocket hole screw driver bit. The 9.5mm diameter stepped titanium bit is specifically designed for pocket holes and has a wide flute for optimum swarf clearance. The titanium coating reduces friction and leaves a clean side hole. The depth stop collar is bored to a precision fit and when locked onto the shank with the supplied allen key will not slip. The square driver bit measures 150mm in length and has an industry standard 1/4" hex shank. This set makes an excellent upgrade or spare back up set for all leading brands of pocket hole jigs. ©
