  • Mfr #: 427A156
  • High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
  • Black oxide treatment adds lubricity and creates small pockets on the surface of the tool that act to hold coolant near the cutting edge
  • These round shank tools have flats ground onto three sides to reduce slippage of the bit when used in drill chucks
  • When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging
  • They are tapered at the point to facilitate entering of holes which are out of alignment
