Metal Hole Saw Drill Bit, Tungsten Carbide Tooth Hole Cutter for Stainless Steel Sheet, Metal, Alloy, Iron, Wood (70mm)

Industrial Grade Metal Hole Cutter - Made of carbide with a tungsten tip for exceptional cutting performance and durability. Cut Perfect Circles - Quickly and accurately cuts holes in stainless steel, metal, iron, alloy, brass, wood, etc. More Efficient - The sharp, hardened tip with an optimized design penetrates the material easily and smoothly. Versatile - The 3-surface, anti-slip shank design allows for use with hand drills, bench drills, magnetic drills, and other rotary machines. Warm Tips - Keep the drill running smoothly at a low speed to extend the cutter's lifespan. Please add coolant when working on stainless steel and steel sheets thicker than 5mm. Product Features: 1. Made of tungsten carbide alloy steel, hardened to HRC64-65 for extended life. 2. Three-edged teeth for fast drilling speed. 3. The chip evacuator quickly removes iron chips. 4. The stepped pilot drill bit is designed to protect the tungsten carbide tip from impacts. Installation steps: 1. Use the hex key to loosen the set screw. 2. Align the top notch of the pilot drill bit with the hole in the set screw and tighten to ensure the center drill bit is stable. 3. Install the TCT carbide drill bit on the electric drill, bench drill, or magnetic drill and begin drilling. Applications: - Smoothly cuts materials up to 5 mm thick, such as stainless steel, sheet metal, high-alloy steel, iron, aluminum, plastic, FRP, and PVC. -Widely used for home decoration, for example, for drilling holes in metal kitchen panels, door frames, and wiring boxes. -Heavy use in industrial settings, for example, in heating, ventilation, and air conditioning applications, requires a durable hole saw that allows for precise cutting in high-quality stainless steel. -Precise drilling for electrical boxes to smoothly assemble knobs, switches, and displays. Caution Tips: 1. Install and tighten manually before use. 2. Use on electric drills and bench drills that can accommodate a shank larger than 10 mm. 3. Keep the drill steady while drilling; otherwise, the center bit may break due to excessive shaking. 4. The hole saw may overheat due to rapid rotational friction; please use cutting fluid to keep the hole saw cool during use.
