Step Drill Bit 3.2 mm HSS M35 with Cobalt Seven-Step Tip Length 65 mm Cylindrical Shank Drilling Iron Steel and Stainless Steel
You already have the maximum available quantity in your cart.
The spiral drill bit with a step tip has a diameter of 3.2 mm and is designed for drilling holes in metal materials. The material is high-speed steel HSS M35 with cobalt, suitable for drilling iron, common steel, and stainless steel. The tip of the drill consists of seven small steps that gradually transition to the full diameter. The spiral groove along the entire working part removes chips from the hole. The drill bit is used by locksmiths, machine repairers, and DIY enthusiasts working with sheets and profiles.
The working part with the spiral measures 36 mm, and the total length of the drill bit is 65 mm. The drill bit is clamped via the cylindrical shank into the chuck of a hand drill, cordless drill, or pillar drill. The diameter is marked on the shank, making it easy to distinguish the drill bit from other sizes in the case. The stepped shape of the tip is visible in the detailed product images and differentiates this drill bit from standard spiral drill bits.
This model differs from a classic spiral drill bit by its tip, which has seven steps with increasing diameter. The narrowest step at the tip creates a small hole in the metal, and the subsequent steps gradually widen it until the full diameter of 3.2 mm penetrates the material. The hole is therefore created in several stages during a single pass. The steps on the tip are clearly visible in the detailed product photographs, as well as the trace they leave in the wall of the hole. The drill bit is intended for drilling into metal, particularly iron, structural steel, and stainless steel, both in hand and pillar drills.

For drilling into steel and stainless steel, we recommend using cutting oil or coolant, which reduces overheating of the tip. Adjust the speed according to the small diameter of the drill bit and the hardness of the material, and keep the drill bit perpendicular to the drilled surface. Excessive pressure is not necessary. After use, clean the drill bit of chips and oil residues and store it separately to prevent the tip from becoming dull from contact with other tools.
The 3.2 mm drill bit with a stepped tip is a useful tool for both workshop and home. Thanks to the HSS M35 steel with cobalt, it can also handle drilling into stainless steel. The seven steps on the tip gradually enlarge the hole to the full diameter. The cylindrical shank can be clamped into a standard chuck. The package contains one drill bit with a diameter of 3.2 mm.
