Countersink drill bit set in 7 different sizes (3 mm/4 mm/5 mm/6 mm/7 mm/8 mm/10 mm) including Allen key and storage case. Numbering makes identification easy, making the set versatile and easy to transport and store. User-friendly design: The Allen key allows you to remove the five-sided chamfer or adjust the countersink and drilling depth for screws of different lengths. Versatile use: The countersink drill bit set includes 1 Allen key and 7 countersink bits in 7 different sizes to meet all your needs. Three-step application: Step 1: Set the desired length using the Allen key. Step 2: With 3 applications per week, visible results can be expected after 2 to 4 weeks. Press and hold the on/off switch for three seconds to turn on the device and select the suction power. Step 3: Drill vertically to the desired depth. The depth should be chosen so that the screw head is flush with the surface. Ideal for wood, fiberboard, chipboard, plywood, plastic, PVC, rubber, etc. Suitable for bench drills, hand drills, and conventional electric drills. Tips: 1. The drill bit must be held perfectly perpendicular while drilling! Otherwise, it can easily break. 2. Simply replace damaged drill bits. 3. We recommend using a drill; it will produce better results than a hand drill, which is not fixed in place during operation and can bend or break.
