Product description

  • High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance
  • Combination black and gold finish, for improved lubricity, corrosion resistance, and to reduce chipping or flaking
  • 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
  • Construction reamer is especially adapted for heavy duty reaming as encountered in the fabrication of structural steel assemblies
