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.
