Drills & Countersinks

C6 Drills & Countersinks

Whether designed as single drills and countersinks or as a combined drilling and countersinking solution in one tool, we have an economical solution for all your applications in the field of modern materials. Our aim is to perform drilling and countersinking operations in One-Shot, i.e. in one production step, without rework.


  • Fast reaction times for new developments and optimizations, no long delivery times
  • Smooth running, low cutting pressure, low vibration
  • Long tool life due to special diamond coating process matched to C6 drill geometries
  • Rework-free hole edge quality (no reaming or manual reworking)


  • Drilling / countersinking of CFRP (carbon fibre reinforced plastic) components in series production with long service lives due to special diamond coatings
  • Drilling / countersinking of stacks (CFK-Al or Al-CFK or CFK-Al-CFK or Al-CFK-Al)
  • Drilling / countersinking of SMC (Sheet Molding Compound) components in series production without reworking of the milled edge (no manual grinding process)
  • Drilling / countersinking of CSMC (Carbon Sheet Molding Compound) components in series production
  • Drilling / sinking honeycomb in the aerospace industry
  • Drilling / countersinking of aluminium profiles in rail transport
