Feature

●Better performance: the conical drill is made of M2 high-speed steel, which has high toughness, wear resistance and good cutting performance. The pointed tip and wide groove ensure fast and clean drilling of pilot holes and ensure a tight fit for screws.
●Counter hole: #45 carbon steel adjustable four-cutter counter-bore with chamfer angle of 82 degrees allows faster machining and self-cleaning drilling on the chips to get a beautiful tapered counterbore when drilling the pilot hole.
●Adjustable: The counter bore feature attaches surfaces to the shaft with 2 hex screws for a secure fit and can adjust the total length of the bit and thus control the depth of the pilot hole.
●Size: the wood drill is equipped with 5 different sizes: 7/64 inches (2.8 mm), 9/64 inches (3.6 mm), 11/64 inches (4.4 mm), 3/16 inches (4.8 mm), 7/32 inches (5.6 mm), which cover the entire screw size range and meet your different needs.
●Quick change: the 1/4 inch hex shank can be used with drills and quick-change chuck. Perfect for wood, fiberboard, chipboard, plywood, plastic, PVC, rubber, etc.
