Overview
4.5 mm Spiral Drill Bit with Step Tip HSS M35 Cobalt Seven Steps Total Length 80 mm Cylindrical Shank for Drilling into Steel and Stainless Steel

The spiral drill bit with a step tip and a diameter of 4.5 mm is designed for drilling holes in metal. The material is high-speed steel HSS M35 with Cobalt, used for drilling iron, standard steel, and stainless steel. The tip of the drill consists of seven small steps that gradually lead to the full diameter. The spiral groove removes chips from the hole during operation. The 4.5 mm size is among the commonly used diameters when working with sheet metal and metal profiles.

The drill measures a total of 80 mm, of which 48 mm is allocated to the working part with the spiral. The length is suitable for drilling into sheets, strips, square tubes, and other metal profiles. The cylindrical shank can be clamped into the chuck of a cordless drill, hand-held electric drill, or pillar drill. The shape of the step tip is clearly visible in the detailed photographs.

Unlike a regular spiral drill, the tip of this model is divided into seven steps with increasing diameters. The first step creates a narrow hole in the material, and each subsequent one slightly enlarges it. The full diameter of 4.5 mm is achieved only after passing through all the steps. This allows for creating a hole in one go, and pre-drilling with a thinner drill is not necessary. Product photographs also show the traces of the steps in the wall of the hole.

For drilling into steel and stainless steel, it is advisable to use cutting oil or coolant, which reduces the heating of the tip. Choose the speed according to the diameter of the drill bit and the hardness of the metal, and keep the drill bit perpendicular to the surface without excessive pressure. After completing the work, clean the drill bit of chips and oil residues and store it separately from other tools to prevent the tip from dulling. The 4.5 mm size is suitable for holes for screws and rivets in sheet metal covers, for attaching metal strips and brackets, or for modifying shelves and frames. It is also useful for repairs of metal gates, fence panels, and garden equipment. It is advisable to mark the future hole location with a centre punch beforehand to prevent the drill bit from slipping at the start.

The 4.5 mm step spiral drill bit will be useful in the workshop, garage, and during home repairs of metal structures. The cobalt steel HSS M35 can also handle drilling into stainless steel. The seven steps on the tip gradually enlarge the hole to the full diameter. The cylindrical shank fits into any standard drill. The packaging contains one drill bit with a diameter of 4.5 mm.
