Special featuresThe Makita Quad Driver makes it easy to perform multiple tasks with a drill/driver. The drill side creates a quick and clean (countersunk) drill hole of 3.2mm. The Quad Driver can then be quickly reversed using the black locking ring. With the PH2 screw side, a 5mm screw can then be screwed into the material in an instant. An Allen key is located on the underside of the Quad Driver. This can be used to replace the drill with a different diameter or the screw bit with a different fitting in 25mm hex form, if desired.
