92mm HSS M42 bi-metal high-speed steel hole saw with hexagonal shank and drill bit for wood, drywall and sheet metal, black,--

Numerous 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, robust and abrasion-resistant. The high-speed steel teeth are heat-treated, high hardness (65HRC), reusable, and durable. Easy to use: Thanks to its clean-edged design, this hole saw cuts easily and effortlessly. The spring around the drill bit automatically pushes the saw's crown immediately after the hole is finished. Can be used with a standard adapter in all drills with an SDS-plus or hexagonal chuck. New design: The pre-drilled holes have a beneficial effect on the drill bit's development, improving the speed of removing cylindrical threads trapped in the hole.
