Overview
3 mm HSS M35 Cobalt Step Drill Bit Seven Steps on the Tip Total Length 61 mm Cylindrical Shank For Iron and Stainless Steel

The step drill bit with a diameter of 3 mm is designed for drilling small holes in metal. It is made from high-speed steel HSS M35 with cobalt content, which is used for more demanding drilling into iron, steel, and stainless steel. A unique feature of this drill bit is the tip formed by seven small steps that smoothly transition into the full diameter. The spiral flute removes chips from the hole during drilling. The drill bit is suitable for metal workshops, construction sites, and for DIY enthusiasts who need a precise hole with a small diameter.

The total length of the drill bit is 61 mm, of which 35 mm is the working part with the spiral. The short design is typical for small diameter drill bits and facilitates the guidance of the drill bit during manual work with a drill. The cylindrical shank is clamped into a standard drill chuck, cordless drill, or pillar drill. The diameter of the drill bit is marked on the shank, making it easy to find among other tools. The stepped geometry of the tip is clearly visible in the detailed product photographs.

The main difference compared to a standard spiral drill bit lies in the tip, which has seven steps with gradually increasing diameters. The smallest step at the tip creates the first small hole in the metal, and each subsequent step enlarges it slightly until the full diameter of the drill bit penetrates the material. Thus, the hole is formed gradually in several stages during a single pass of the drill bit. This shape is clearly visible in the detailed photographs, where the trace left by the individual steps in the wall of the drilled hole can also be seen. The drill bit is intended for metallic materials, primarily for iron, standard structural steel, and stainless steel.

When drilling into metal, choose speeds appropriate for the small diameter of the drill bit and the hardness of the material. When working with steel, especially stainless steel, it is beneficial to use a coolant or cutting oil, which reduces the heating of the tip. Always guide the drill bit perpendicular to the surface and do not apply excessive force. After use, clean the drill bit of chips and store it in a way that prevents the tip from being damaged by other tools.

The 3 mm step drill bit is a practical addition to any metal tool set. The high-speed steel with cobalt makes it suitable for drilling into stainless steel. The tip with seven steps gradually enlarges the hole to the full diameter. The cylindrical shank ensures easy clamping into a standard drill. In the package, you will receive one drill bit with a diameter of 3 mm, ready for immediate use.
