Stepped drill bit with unique SMART STEP technology and dynamically curved rake between the individual step transitions for extremely fast and comfortable use in all common materials with a material thickness of up to 3.5 mm.

Dynamically curved rake between each step transition


  • Significantly longer service life compared to conventional stepped drill bits

  • Significantly faster drilling compared to conventional stepped drill bits

  • Little effort required

  • Smooth, perfectly controlled drilling process

  • Greatly reduced formation of burrs


SMART STEP technology


  • Up to 3x faster tapping compared to conventional stepped drill bits

  • Precision tapping without centring or centre-punching

  • No warping of sheet metal

  • Simple boring or enlarging of an existing drill hole

  • No rattling or catching in the material

  • Precise, circular drilling without tearing or splintering


Deep-ground spiral flute


Excellent chip removal



3-flat shank


  • No spinning in the drill chuck: faster, more comfortable working

  • Optimal power transmission

  • Protects the drill chuck from damage

  • Little effort required to loosen and tighten the drill chuck


Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified® Bronze

Application area
  • The ideal tool for machining sheet metal.

  • Centring, spot drilling, boring and deburring of sheet metal, tubes and profiles in one operation, for use on both hand drills and stationary equipment.

  • Ideal for use in electrical trade, plumbing and heating systems, automotive workshops, mechanical engineering, switch cabinet manufacturing or container and equipment engineering.
Instructions
  • Ensure that there is sufficient coolant/lubricant

  • Observe the rotation speed table

  • Do not push during boring. The stepped drill bit automatically retracts into the sheet metal
