Product information

  • Using the KARL® depth-stopping drill bit—which consists of a ball-bearing-mounted depth stop and the KARL® facade drill bit—ensures the correct drilling depth.
  • The KARL® depth-stopping drill bit is clamped into the chuck of a cordless drill/driver.
  • For use in a CNC machine, only the KARL replacement drill bit is used.
  • The drill bit can be replaced in a resource-efficient manner by removing it from the stop and replacing it with a new KARL® facade drill bit.
  • The KARL® facade drill bit, made of carbide, is available in the appropriate length to match the KARL undercut anchor.

Application

  • Fiber cement
  • High-pressure laminate (HPL)
  • Compressed fiberboard

We would be happy to test the usability of our undercut anchor in your material as well.

Instructions for use

  • Application according to KARL assembly instructions.
  • The drill hole depth is ensured by using the KARL depth stop.
  • For use on the construction site, it is recommended to use a cordless screwdriver.
  • In the case of industrial prefabrication, the drill can also be clamped in a CNC machine without the KARL depth stop.
