  • Designed to resize drilled and bored holes to precise size diameters.
  • Spiral flute design gives these reamers a shearing cutting action making them better suited for materials normally difficult to ream.
  • Round straight shanks may be mounted in chucks, collets or similar toolholders and may be used with a variety of standard portable or stationary machines.
  • Used to produce accurate holes in a variety of normal ferrous and non-ferrous materials.
  • Combination of flute depth and shank diameter help to ensure adequate space for chips and reduce the contact area to reduce heat build-up.
  • Suitable cutting oils or appropriate coolant fluids are recommended for most reaming operations.


  • Right hand (clockwise rotation) cutting direction.
  • Standard 45° chamfered cutting edge.
  • Overall length, flute length and shank diameter are sized proportionally to cutting diameter for maximum rigidity.
  • Easily resharpened.
