Special Features
【7-Piece Countersink Bit Set】 Includes 4 commonly used wood countersink bits, an adjustable depth stop ring, 1 L-shaped wrench, and 1 S2PH2 screwdriver bit. This tool is designed to drill pilot holes and chamfer edges in a single operation, facilitating the installation of flat-head screws.
【High-Quality Materials】 The drill bits are made of highly resilient M2 high-speed steel, making them resistant to bending and breaking; the tungsten carbide cutting edges are 30% sharper than ordinary steel, ensuring burr-free holes with smooth cut surfaces, excellent countersinking and countersinking results, and a longer service life.
【Sizes】The four drill bits are sized at 7/64'‘ (2.8 mm), 1/8'' (3.2 mm), 9/64'‘ (3.6 mm), and 5/32'' (4.0 mm). The countersink diameter is 3/8'‘ (9.5 mm), with an adjustable depth range of 0–1/2''. The drill bit features a 1/4-inch hex shank, making it compatible with most woodworking tools.
【The depth stop ring allows for precise depth adjustment】 The aluminum alloy depth stop ring features a built-in ball bearing that stops rotation immediately upon contact with the wood, reducing wear by 90% compared to traditional depth stop sleeves. When used with the included hex screws, you can freely adjust the drilling and countersinking depths, ensuring consistent machining accuracy and eliminating issues such as over-drilling and friction burns on the wood.
【Versatile for Multiple Materials】Can be used on hardwood, MDF, plywood, particleboard, outdoor decking, drywall, and plastic; suitable for both DIY projects—such as building custom furniture or constructing a deck—and professional woodworking tasks. We recommend keeping the speed at 200 RPM for smooth, burr-free holes.
【Compact and portable】The entire set of drill bits is stored in a lightweight, compact toolbox weighing just 0.33 pounds. The box features hanging holes for wall mounting or carrying on the go, keeping the drill bits neatly organized and well-protected—convenient for both job sites and home use.
