Execution

  • The use of coolant is recommended to increase the service life.
  • Centre punching, drilling and deburring in one step
  • Rapid Strike drill tip for easier centring - no "wandering" of drill bit and fast drilling progress without the need for pre-drilling.
  • Special drill tip and a special step geometry enable chatter-free drilling. Reduced risk of tilting or deformation of the material to be drilled at high speeds
  • Optimised two-spiral geometry with sharpened edges for up to 2x faster drilling progress
  • Manufactured from special steel with black oxide coating for up to 4x longer service life.
  • Optimised for use in cordless tools.
  • Laser marking of diameters for long-lasting readability.
  • Each step is relief ground for optimal drill feed and automatic deburring.

Advantage

  • Shank with three clamping surfaces for secure retention in the drill chuck and optimal power transmission.
