Countersink Drill Bit Set: Set includes depth stop, hex wrench, and four interchangeable drill bits with different diameters (2.8 x 8mm, 3.2 x 8mm, 3.5 x 10mm, 4.0 x 10mm). Each bit is equipped with a 3/8-inch 82° countersunk hole and a 1/4-inch hex shank, suitable for multiple types of tools such as power screwdrivers, impact drills and more
Depth Adjustment: The drill bit set comes with a side scale to visualize the screw length. You can easily adjust the drilling depth by using the included hex wrench. The built-in depth limiter allows for consistent hole depth and ensures accurate drilling every time, meeting the needs of furniture assembly, modeling and other precision drilling
Robust and Durable: The countersunk drill bits are made of high-strength alloy with excellent cutting performance and wear resistance. The edge of each drill bit is precision ground to cut smooth and burr-free holes, reducing subsequent trimming work. The unique helical edge design helps to quickly discharge chips from the hole, improving the smoothness and efficiency of the drilling process
Easy to Change: The included hex wrench makes it easy to change inserts and bits, reducing the time required for frequent tool changes. The hexagonal shank design ensures that the drill bit is stable at high speeds, keeping the tool in optimal working condition. The set comes with an easy-to-carry storage case that neatly organizes the countersunk drill bits and ensures that the tools are well organized, making it an ideal choice for woodworkers and hobbyists
Versatile Applications: The depth adjustable countersunk drill can enhance your woodworking and is suitable for a wide range of materials such as wood, plastic and fiberboard. Easily adjust the depth with a wrench to get the desired results with ease. NOTE: For best results and smooth edges, it is recommended to operate the countersunk hole at a low speed of approximately 200 rpm. Not recommended for metal and sheet steel machining
