Specially designed cemented carbide plate geometry (multi-surface precision grinding)


  • Highly accurate spot drilling

  • Precise and break-out-free drilling


No cooling required


Dry drilling

Notice
  • Max. Rotation speed 200 rpm

  • Not suitable for impact drilling. For rotary drilling only!

  • Optimum contact pressure 35–45 kg

  • If the recommended drilling speed is observed and the optimum contact pressure applied, but you can no longer hear a "scraping" sound, the drill bit has reached the end of its service life.

  • Avoid placing high contact pressure on the drill bit when it is not rotating→ Risk of breakage!

  • Contact pressure too low and/or drilling speed too high → Service life ends prematurely!

  • Avoid tilting and swivelling movements during the drilling process → Risk of breakage!

  • We recommend drilling test holes (ideally in the waste material of the tile to be drilled)

  • When using the 14-mm diameter drill bit, a pilot hole must be drilled with the additional enclosed drill bit (8 mm).
