Product information

  • The KEIL façade drill bit is available in various designs matching the KEIL undercut anchor.
  • We offer diamond or carbide tipped façade drill bits, which are used depending on the panel material to be drilled.
  • Optimized, small diameters with large undercutting cause minimization of the drilling time and maximization of the tool life.
  • The KEIL drilling technique warrants optimally short drilling times, long tool life and precise drill hole geometry.


For façade panels from e.g.

  • Fibre cement
  • Laminate (HPL)
  • Synthetic materials
  • Specified artificial and natural stones
  • Solid surface materials

Instructions for use

  • Use according to approval and KEIL assembly instructions for anchors. Please find documents with relevance to building regulations under certificates.
