Toolex Hand Reamer - Spiral Flute - Straight Shank - HSS - H5 - 12.71mm

The Toolex Hand Reamer is a precision finishing tool designed to bring internal diameters to exact sizes with consistent finishes. Built from high-speed steel (M2) and paired with a straight shank, it is compatible with standard hand reaming setups for reliable performance across metalworking projects.

With a 12.71 mm nominal diameter and a left-hand spiral flute paired to right-hand cutting, this reamer follows DIN 206-B geometry and ISO H5 tolerance, delivering precise results you can rely on. Manufactured to order by Toolex Ltd, please allow 24–48 hours despatch; note that stock status refers to blanks ready for machining the reamer.

• Left-hand spiral flute with right-hand cutting: The fluted design channels chips efficiently during reaming, reducing chatter and delivering smooth, accurate hole finishes with predictable guidance.
• DIN 206-B, ISO H5 tolerance: Ensures tight dimensional control so holes clean up cleanly with minimal finishing work, improving part fit and assembly reliability.
• M2 HSS with straight shank, made to order: High-speed steel provides wear resistance and edge retention for repeated use; the straight shank fits most hand reamers and fixtures, and the made-to-order process enables precise lead times (24–48 hours despatch).

Using this reamer helps you achieve consistent hole sizes quickly, reduces downtime due to rework, and improves surface finish quality. The combination of M2 HSS, spiral flute geometry, and DIN/ISO tolerances supports reliable, repeatable performance across a range of materials, enabling faster setup, fewer passes, and better overall results in precision assemblies.
