  • High Speed Steel - The step drill bit is made from high speed steel of high hardness and good wear resistance. Surface is coated with titanium which give the drill bit a beautiful gold color and will not fade easily.
  • Widely Used - Step drill is great for use in work where thin steel, aluminum or plastic boxes and chassis are encountered. It is most commonly used on softer materials such as thin iron sheet, aluminum, PVC and wood board of 5mm or thinner.
  • Easy Drilling - Easily identify which size you need with the contrasted, laser engraved sizes inside the step drill bit flute. Two-Flute Design for smoother cutting. High Step design let you feel the stop and never drill bigger in mistake.
  • Dual Groove Design - Step drill bit grooves provide a smoother cut that removes burr chips, dust and chips for faster chip evacuation, while helping to prevent chips from flying, allowing for smoother drilling without heating.
