Perfect drilling results due to unique drilling technology.

With its specially developed cutting geometry, the carbide core drill bit achieves the desired hole diameter with little effort on the user’s part.

How the new drilling technology works:

  • The pilot bit projects 1 in (25 mm) for exact positioning at the drilling location.
  • ¹³⁄₁₆ in deep center drilling at 1600 rpm followed by decoupling of centring drill and automatic change of speed to 520 rpm to set optimum cutting speed for carbide core drill.
  • The user’s entire feed force is transferred to the carbide core bit.
  • At material breakthrough, a spring pushes the pilot bit forward to eject the core.
