For metalworkers and maintenance technicians who need clean, burr-free holes in thin sheet metal, the RUKO BSB step drill bit cuts through non-ferrous metals, plastics, and sheet steel with a single tool. Its 9 steps from 4 mm to 20 mm in 2 mm increments eliminate the need for multiple drill bits when working on control panels, enclosures, or ductwork.

Key specifications

  • Material: High-Speed Steel (HSS)
  • Diameter range: 4–20 mm
  • Number of steps: 9
  • Step increments: 2 mm
  • Shank type: Cylindrical
  • Shank diameter: 10 mm
  • Flute type: Spiral
  • Point angle: 118°
  • Cutting direction: Right-hand

Why choose it

The spiral flute design clears chips efficiently, reducing heat build-up and prolonging tool life. The 118° point angle provides a good balance of centering and cutting performance in thin materials, while the uncoated HSS body can be resharpened when dull.

Ideal use cases

  • Drilling sheet metal up to 4 mm thick
  • Enlarging existing holes in plastic or aluminium
  • Creating knock-out holes in electrical cabinets
  • Deburring and chamfering in one operation

Good to know

The step drill bit is intended for use in a drill press or handheld drill with a 10 mm chuck. Apply cutting fluid when drilling steel to maximise tool life.
