Product description

  • For general purpose drilling in applications where extra length for reach is required, designed to perform in a broad range of materials in the iron and steel families
  • Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
