Description

Size - Cutting diameter: 19.5mm / 0.77" (49/64"); cutting depth: 14mm / 0.55"; triangular shank size: 8mm / 0.31"; total length: 70mm / 2.76" Material - M35 HSS (high-speed steel) contains 5% cobalt, offering high hardness, high strength, heat resistance, durability, wear resistance and impact resistance. It is more durable than ordinary high-speed steel, and can maintain hardness and cutting ability even after long-term use. Feature - The fully ground teeth make precise cuts, creates a smoother cut and reduces the amount of burring or chipping. It is are more durable, and can be sharpened more easily. Titanium plating provides durability, corrosion resistance, wear resistance, and lower coefficient of friction. Applications - The hole saw cutter is suitable for cutting stainless steel, aluminum alloy, copper, brass, metal, wood and plastic. Widely use in pipes, tubes, plates, furniture making, door knobs, cabinet pulls and DIY projects , great for woodworking, metalworking, plumbing. Note - NOT recommended for ceramic tile, concrete, stone, and not for metal over 5mm thick. Used with hand-held drills, drill presses, and rotary tools. Use a lubricant or cutting oil, apply correct speed and even pressure, clear the chips from the hole frequently. Comes with a plastic case for protection and storage.

The hole drill bit can be used with hand-held drills, drill presses, and rotary tools. A drill press provides precise control over the drilling process, making it an excellent choice for drilling multiple holes or drilling through thick materials. Keep the hole saw steady while drilling.
Notice: NOT recommended for ceramic tile, concrete, stone, and not for metal over 5mm thick. Use a lubricant or cutting oil on the cutting edge to reduce friction and prevent overheating, resulting in longer tool life and smoother cuts. Apply correct speed, even pressure, and clear the chips from the hole frequently to avoid clogging. Pay attention to the cutting process and adjust the speed as needed.
