The sheet metal conical drill bit with unique SMART STEP technology and spiral groove for extremely fast, comfortable and precise use in all common materials with a material thickness of up to 4 mm.

SMART STEP technology


  • Up to 3x faster tapping compared to conventional sheet metal conical drill bits

  • Up to 50 % longer service life compared to conventional sheet metal conical drill bits

  • Significantly less effort required when drilling compared to conventional sheet metal conical drill bits

  • Saves pre-drilling, precise tapping without running off centre

  • Comfortable, stepless boring or enlarging of an existing drill hole

  • Burr-free drilling without deformation of the sheet metal

  • Precise, circular drilling


Deep-ground spiral flute


Excellent chip removal



Laser scaling in the flute


Easy reading of the hole diameter during the drilling process



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



Available exclusively from Würth

Application area
  • The universal tool for large, stepless drilling in 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 the 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 sheet metal conical drill bit automatically retracts into the sheet metal.
