[Pre-drilled holes and countersinks] A set of 22 pre-drilled holes and countersinks. [Adjustable countersink depth] By moving the position of the drill stopper, you can easily adjust the depth of the pilot hole, allowing you to drill pilot holes to a uniform depth. [High-speed tool steel] By using high-hardness M2 high-speed tool steel and applying a nitriding treatment to the surface, wear resistance, fatigue resistance, and corrosion resistance are improved, maintaining a long service life. High-Speed Cutting: The dual-flute, 82° point angle drill easily penetrates the workpiece, improving cutting efficiency and producing a clean cut. It's ideal for a variety of woodworking projects, including cabinet and furniture manufacturing. (Note: While this product is compatible with electric drills, cordless electric drills, and bench drills, we recommend using it with a benchtop drill for optimal cutting results with countersink drills.)
