Wood Drill Bits

Drill bit for timbering, round shank

  • Safety specification according to the Employer‘s Liability Insurance Association for Wood standard
  • Optimum removal of drilling dust
  • 90° tip angle
  • Blasted surface
  • In all rotary and percussion drilling machines
  • To break through outer and inner covering boards in one operation
  • Largest clamping shank (d) 13 mm Ø


  • These drill bits meet the requirements of the safety specifications of the Employer's Liability Insurance Association to DIN 7490, have a large chip flute up to the chip exit and are made of one piece for perfect true running
  • Breakage of the drill bit, which can occur with glued or welded timbering bits, is impossible due to the one-piece design
  • This results in being a true safety installation drill bit
  • The designs with round shank as well as those with SDS-plus shank permit a use of these drill bits with almost all rotary, percussion and hammer drilling machines (with hammer action switched off).
