The kit includes a 23-piece woodworking countersink set: six 90° 5-flute HSS countersink drills with 1/4-inch hex shank; seven 3-point HSS countersink drills (including an L-wrench for adjustments when drilling or countersinking); a set of 8 plug cutters; and an automatic center punch for marking workpieces to prevent screws or drill bits from slipping.
The 8-piece plug cutter set has 3/8-inch shanks and is made of durable carbon steel; it is designed to create tapered wood plugs in sizes 1/4\", 3/8\", 1/2\", and 5/8\" to conceal screw heads or imperfections, with cutting lengths of 22 mm, 23 mm, 25 mm, and 26 mm.
The 5-flute countersink drills with 1/4-inch hex shank are made of HSS steel and come in six diameters: 6 mm (1/4\"), 8 mm (5/16\"), 9 mm (3/8\"), 12 mm (1/2\"), 16 mm (5/8\"), and 19 mm (3/4\"); they are used for drilling and countersinking when installing screws and fasteners in wood and PVC.
The 7-piece 3-point countersink set is made of HSS steel and offers excellent wear resistance and reliability; sizes include 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, and 10 mm for drilling pilot holes, with wide chip channels and a five-cutting-edge design for faster and easier sawdust removal.
