SMART STEP technology
- Up to 3x 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
AlTiN multi-layer wear protection coating
- Extremely high temperature resistance up to 1,150 °C
- Very high coating hardness of 3,200 HV
- Multi-layer structure for optimal chip removal and improved cutting properties (prevents material becoming welded)
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
Datasheets(X)
- 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.
- Cooling not absolutely necessary, but significantly extends the service life
- Observe the rotation speed table
- Do not push during drilling out. The sheet metal conical drill bit automatically retracts into the sheet metal.
