Overview
HSS Step Drill Bits 4-12 4-20 and 4-32 mm Set with Case Titanium Coating 118° Point Hex Shank For Metal and Wood

These step drill bits in the set make it easier to drill holes of various diameters in metal, plastic and thin wood. Each drill bit is made from high-speed steel HSS and features a titanium nitride coating that reduces friction during use. The spiral flutes efficiently remove chips from the cutting area, allowing for faster drilling while keeping the bit cooler. The point with an angle of 118° reduces the tendency for the drill bit to slip on the surface and helps to accurately establish the hole. The set includes three sizes with ranges of 4-12 mm, 4-20 mm and 4-32 mm.

Unlike a traditional drill bit, a step drill bit gradually increases the diameter from a small hole to a larger one without changing tools. The diameters are marked on the steps with laser engraving, ensuring they remain clearly readable even after prolonged use. The smallest bit has 9 steps of 1 mm, the middle one has 9 steps of 2 mm, and the largest has 15 steps of 2 mm up to a diameter of 32 mm. The lengths of the drill bits are 73 mm, 78 mm and 103 mm. The drill bits are designed for materials up to 4 mm thick, such as thin steel sheets, aluminium sheets, insulation panels, PVC boards or wooden planks and boards.

  • Lengths of Drill Bits – 73 mm, 78 mm and 103 mm
  • Shank – hexagonal, slip-resistant in the chuck
  • Diameter Markings – laser engraving on the steps
  • Recommended Material Thickness – up to 4 mm
  • Contents of Package – 3 spiral step drill bits (4-12 mm, 4-20 mm and 4-32 mm) and a black case

For the best results, mark the drilling spot in advance and hold the drill bit perpendicular to the material. For metal sheets, use lower speeds and consistent pressure; a cooling or lubricating fluid can help during prolonged use. After completing the work, wipe the drill bits clean of chips and store them back in the case to prevent damage to the cutting edges and keep the set together.

This set of three spiral step drill bits is a versatile addition to any workshop or home tool kit. It combines HSS steel, titanium coating, a precise tip, and a hexagonal shank for the drill chuck. The spiral flutes and engraved steps allow for quickly creating an accurate hole of the desired diameter. The case keeps all three drill bits organised and ready for use. It will be appreciated by DIY enthusiasts and craftsmen who regularly drill into metal, plastic or wood.
