Overview
Set of 3 HSS Step Drill Bits Holes up to 20 mm Step 1 mm and 2 mm Titanium Coating Hexagonal Shank 6.35 mm Case for Metal and Wood

The set of three step drill bits is designed for quick drilling and gradual enlargement of holes in thin materials without the need to switch between a range of standard drill bits. The bits are made of high-speed steel HSS and their surface is coated with titanium, which reduces friction during drilling. The two smaller bits end with a diameter of 12 mm, and the largest bit in the set can handle a hole of up to 20 mm in diameter. All three have a hexagonal shank of 6.35 mm, which securely grips in the drill chuck and does not spin during use. The diameters of the individual steps are marked directly on the bits, so you always know what size hole is being created.

What is interesting about this set is the different graduations of the two smaller bits. One of them has steps of 1 mm, allowing you to create a hole exactly as needed, for example, for a cable grommet, screw, or connector. The other smaller bit has steps of 2 mm and starts at a diameter of 4 mm. The largest bit 4-20 mm has nine steps also at 2 mm intervals and is suitable for larger holes for switches, cables, or pipes. The shorter bit measures 67 mm, while both longer bits measure 77 mm. The stepped shape allows you to start with a small hole and then gradually enlarge it without changing tools. These bits are useful in the workshop, during electrical installations, when modifying cabinets, or for model-making tasks.

  • Shank – hexagonal 6.35 mm (1/4")
  • Diameter Marking – marked directly on the individual steps
  • Suitable Materials – thin metal, plastic, and wood
  • Usage – cordless drill, electric drill, and bench drill
  • Package Contents – 3 step drill bits (4-20 mm, 4-12 mm, and a bit up to 12 mm with a 1 mm step) and a black storage case

Before drilling, it is advisable to mark the spot with a centre punch to prevent the drill tip from slipping on the surface. Drill perpendicular to the surface with slight pressure and at lower speeds, especially with metal sheets, where a cooling or lubricating fluid can also help. Upon reaching the desired drilling step, stop and possibly gently deburr the hole. After use, clean the bits of chips and store them back in the provided case, where they are protected and kept together.

This set of step drill bits combines three different tools in one compact package and covers common holes from the smallest diameters up to 20 mm. Thanks to the fine step of one of the bits, you can easily drill holes that must precisely match the size of the inserted part. The HSS steel bits with titanium coating and hexagonal shank quickly clamp into both cordless drills and standard chucks. The practical case keeps the set organised in the workshop, in the tool bag, or in the car. It is a handy tool for DIY enthusiasts, electricians, and tradespeople who frequently drill into metal, plastic, or wood.
