The 2-in-1 product combines two functions in one product: pre-drilling and countersinking up to a diameter of 12 mm in wood can be done in one step - quickly, easily and without changing tools. The flexibly adjustable depth stop ensures the perfect drilling and countersinking depth and the 3 cutting edges provide you with clean results. Ideal for even countersinking in series. The depth stop is made of high-quality plastic and its geometry provides a clear view of the working area and good chip removal. The closed edge ensures even pressure distribution on contact, so that the surfaces of the workpiece are protected. You can change tools in seconds with the ¼″ hexagonal shank.
