The pre-drilling of wood screws takes on a different quality with this countersink drill. Greater tensile strength is achieved with the tapered design than with cylinder drills; at the same time the risk of screw breakage is reduced. The drilling depth is exactly adjustable to the borehole depth by means of an adjusting ring. The countersunk head is also adjustable in depth, so that a dowel can be inserted if required (for invisible screw joins). A steep and deep groove prevents plugging and overheating of the drill. Manufactured in Japan from wear-resistant HSS. 7-piece set: Ø 3.2 / 3.6 / 4.0 / 4.4 / 4.8 / 5.2 / 5.6 mm.
