- 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.
