HSS M42 Bi-metal Hole Saw, 92mm Hex Shank, For Wood, Drywall, Sheet Metal

Multiple Uses: The hole saw is often used in wood, plastic, aluminum, non-ferrous metals, copper, plasterboard, and other materials. Suitable for bench drills, electromagnetic drills, pistol drills, impact drills, etc. Convenient for you. Professional Quality: The bi-metal hole saw is made of high-quality M42 high-speed steel, sturdy and abrasion-resistant. The high-speed steel teeth are heat-treated, high hardness (65HRC), reusable, and durable. Easy to Use: Thanks to its design with clean edges, this hole saw cuts easily and effortlessly. The spring around the drill bit automatically pushes the saw washer back on itself immediately after the hole is cut. Can be used with a standard adapter in all drills with an SDS-plus or hexagonal chuck. New design: Pre-drilled holes have a beneficial effect on chip development, improving the speed of removing cylindrical iron threads from the hole. Product specifications: Material: Bi-metal HSS. Color: Blue (optional). Diameter: 92 mm. Cutting depth: 30 mm. Hole saw assembly: 1. Insert the drill into the chuck and secure the screws on the side of the chuck with a hex key. 2. Insert the chuck down to the tip of the saw blade. 3. Place the mounting plate on the saw, then tighten the nut to lock the mounting plate and prevent damage (the mounting plate must be between the saw blade and the nut). The gasket cannot be installed upside down. 4. Please ensure that the screws are securely fastened to the side of the chuck with a hex key and do not move to guarantee a precise cut. 5. The drill and hole saw are prone to sticking and cannot be removed during use, which can cause the drill to break. Be sure to reduce the drilling speed when using. It is recommended to use machines with a drilling speed of: rpm ≤ 1000 Wh.
