【10-in-1 】Includes 10 carbide hole saws of different sizes-5/8”(16 mm), 3/4”(19 mm), 7/8”(22 mm), 1”(25.5 mm), 1-1/8”(29 mm), 1-1/4”(32 mm), 1-3/8”(35 mm), 1-3/4”(45 mm), 2”(51 mm), 2-1/8”(54 mm), 12 HSS titanium plated pilot drill bits, 2 L-wrenches and 1 aluminum case.
【Three-edge Design】The three-edge design (outer, middle and inner edges) adopted by TCT hole saws improves cutting efficiency and drilling accuracy by dispersing the cutting force, optimizing the chip removal performance and enhancing the stability of the drill.
【High Quality Material】The metal hole saw has tungsten carbide tipped teeth, a HSS titanium plated center drill bit and a 45 steel base. This structure gives the hole saw high hardness, excellent abrasion resistance and good anti-adhesion characteristics, which ensures high efficiency, durability and stability of the drilling process.
【Compatible Machines & Materials】3-Flat three-pronged shank design can provide stable torque transmission, suitable for handheld drills, bench drills, magnetic drills and other drilling tools, applicable to hard metal, stainless steel, cast iron, aluminum, aluminum alloy, carbon steel and other materials.
【Safety Alert】It is advised that you add coolant when drilling at high speed continuously and wear protective glasses and gloves to prevent injuries caused by splashing metal shavings.
