• ISO H5 tolerance: Tight, repeatable hole sizes (-0 to +0.005 mm) reduce rework and improve first-pass results.
• Left-hand flute with right-hand cutting: Promotes efficient chip clearance and stable cutting action across materials for smoother finishes.
• Taper shank, standard length (HSS M2): Easy to fit in standard tool holders with durable wear resistance for repeated use.

This reamer combines precise sizing with practical compatibility, helping you achieve consistent hole finishes quickly while fitting seamlessly into existing tooling setups. Its durable HSS (M2) construction supports longer tool life in demanding applications, giving you reliable performance and fewer tool changes in your milling or drilling workflow.
