Wood reaming drill bit set, equipped with reamers, includes four common sizes (2.8 x 8 mm, 3.2 x 8 mm, 3.5 x 10 mm, and 4 x 10 mm), as well as an adjustable depth stop. It allows you to make screw holes quickly and with great precision. Compatible with most standard electric screwdrivers, this kit includes an Allen key as well as a handy storage case, ensuring easy access and organized storage. With this game you will get impeccable results for all your woodworking projects. These chamfered end mills are made of HSS-M2 steel, which gives them both sharpness and durability. Their unique design incorporates an internal bearing for smooth operation, as well as a front O-ring that instantly stops rotation on contact with the workpiece, preventing excessive drilling or surface scratches. Each cutter is supplied with an adjustable gold anodized aluminum stop ring and a green scratch resistant rubber protective pad, providing double protection for your wood, MDF or chipboard parts. This walnut bit for woodworking is equipped with a manual depth stop that allows for quick and precise adjustment of the drilling depth, without the need for tools. The graduations, easy to read, effortlessly adapt to different lengths of screws. The integrated spring mechanism allows for quick change of the cutter, while the smooth guide ring effectively protects the surface of the workpiece during operation, greatly improving both work efficiency and drilling accuracy. The optimized design for chip evacuation ensures smooth and clog-free drilling at all times. Our countersink drill bits feature a precisely calculated spiral helix and advanced cutting geometry that quickly evacuates chips from the drill hole, effectively preventing their build-up and clogging of the drill bit. This not only keeps the work area clean, but also ensures an uninterrupted workflow, ensuring an efficient, clean and smooth operation. This wood chamfer cutter is suitable for solid wood, particle board, MDF and various wood-based materials. The set includes four sizes (2.8 / 3.2 / 3.5 / 4.0 mm) allowing precise control of the chamfer depth; it is thus ideal for furniture assembly and woodworking projects. For best results, we recommend using a slow rotation speed, approximately 200 rpm. Please note this product is not suitable for use on metal.
