Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 12.70mm

The Toolex Taper Shank Reamer is a long-length HSS (M2) reamer at 12.70 mm diameter, designed for precise hole finishing in deep or hard‑to‑reach features. It uses left-hand spiral flutes with right-hand cutting to deliver stable cutting action and efficient chip evacuation. Supplied by Toolex Ltd and engineered to BS 328/4 with a tolerance of D = ISO H5, this intermediate-precision tool is manufactured to order to ensure accuracy and consistency.

Ideal for engineers, machinists, and hobbyists who need reliable bore finishing, the extended reach of the long-length geometry works well for through-holes and deep pockets, while the taper shank ensures secure seating in standard toolholders. Despatch is typically 24–48 hours after order, reflecting its made-to-order production.

• Long-length taper shank for deep-hole work: The extended length and taper shank provide stable alignment and reach for through-holes and deep pockets, helping you achieve consistent bore sizes.
• Left-hand spiral flute with right-hand cutting: Optimized chip evacuation and smooth, predictable cutting action that improves finish quality and reduces clogging during reaming.
• ISO H5 tolerance with BS 328/4 compatibility: Tight, repeatable hole sizes and reliable engagement in common machine setups, giving you confidence on every job.

By delivering precise bore sizing with reliable surface finish and repeatable results, this reamer speeds up workflows, reduces the need for rework, and fits easily into standard machining setups. The combination of M2 HSS material, long flute geometry, and strict ISO/H5 tolerances makes it a dependable choice for production, maintenance, and repair tasks alike.
