Suitable for metals (steel, castings, aluminum alloys), metal tubes, plastic plates, galvanized tubes, fire hoses, various types of wood, plasterboard, etc. Compatible with drill press, radial drills, pistol drills and other portable drills. Cutting design: The high-speed steel (HSS) bit has anti-shock teeth effectively preventing tooth breakage. Clean cutting edge design without blocking ensures a smooth cut. After drilling, the spring on the bit automatically ejects the hole saw. Wood hole saw kit uses quality high-speed carbon steel, while hole saws are heat treated M42 band. The curved design and concentric precision ensure uniform teeth, extending tool life. Precautions: When using for a long time, maintain a suitable speed (rpm ≤ 1000) to avoid premature wear. A thin layer of protective oil (anti-oxidation/rust) is applied to the surface: avoid contact and regularly check the condition of the hole saws.
