4-32 mm Step Drill Bit, 15 Levels, Conical, Professional HSS, 10mm Triangular Shank, for Screwdriver on Metal, Steel, Wood, Brass, Aluminum, Plastic, Glass -

15 Steps: You can drill suitable holes from 4 to 32 mm (4 mm/6 mm/8 mm/10 mm/12 mm/14 mm/16 mm/18 mm/20 mm/22 mm/24 mm/26 mm/28 mm/30 mm/32 mm) using step drill bits without frequently changing bits, saving you a lot of time. Precision Drilling: The 4-32 mm precision metal step drill bit, with its ultra-deep 4 mm chip evacuation groove, allows for precise step drilling. It effectively removes burrs, producing clean and smooth hole walls, and ensuring accuracy at every step for perfect drilling results. Reliable Performance: This HSS triangular step drill bit for metal, from 4 to 32 mm, is compatible with various electric drills, impact drills, and hand drills. Its reinforced design significantly reduces the risk of breakage under heavy loads, allowing it to easily drill through metal, wood, or plastic and ensuring reliable, long-lasting performance. Instructions for use: When drilling hard materials, metal step drill bits are susceptible to softening and damage from overheating. It is essential to use a cutting fluid for continuous cooling to extend their lifespan; furthermore, the larger the hole diameter, the lower the rotation speed should be to preserve the cutting edge. Durable: Made of high-speed steel (HSS), this step drill bit offers excellent wear and heat resistance. For optimal longevity, it is recommended to use a coolant when drilling metal. Secure grip: The step drill bit features a 10 mm triangular shank that fits perfectly into the drill chuck, eliminating any risk of slippage, even under high torque. This design ensures a firm hold and extremely stable and secure use.

Precautions

Cooling: When drilling hard metal materials, it is essential to use a liquid cooling system such as water to continuously cool them. This prevents overheating, which can lead to softening and discoloration of the steel, and thus prolongs the tool's lifespan.

Speed: Adjust the speed of your machine according to the diameter of the hole being drilled. The larger the diameter, the lower the rotation speed should be.
