About this product
A shell-style 90-degree countersink made from carbon steel, designed with multi-tooth deep ground gullets to leave a clean cut finish. It clamps onto any drill bit between 3.0mm and 7.2mm in diameter, with the drill passing through the body and secured by two hexagon bolts at the required position. Drills are not included. Recommended for use with wood and man-made boards, it is not suitable for ferrous or non-ferrous metals, abrasive materials, or production applications. By reversing the countersink on the drill, it can also be used as a non-cutting depth stop. Users should ensure the flutes of the drill align with the flutes of the countersink and avoid overtightening the screw.
