Manufactured to BS 328/4 by Toolex Ltd, this reamer adheres to ISO H5 tolerance to ensure repeatable bore sizes across production runs. It is manufactured to order, with despatch typically within 24–48 hours.

• Long-length taper shank: Extends reach and maintains stable alignment for deep-hole finishing, improving bore accuracy.
• Left-hand spiral flute with right-hand cutting: Enables efficient chip evacuation and consistent cutting action for clean bore finishes across materials.
• ISO H5 tolerance with HSS M2: Delivers durable cutting performance and tight, repeatable bore sizes in production runs.

With this reamer, you gain a reliable, repeatable bore finish even in long holes. The M2 HSS material resists wear for longer tool life, while the ISO H5 tolerance minimizes additional finishing work. The taper shank design helps you fit standard tool holders securely, reducing setup time and downtime in busy workshops. Built to the BS 328/4 specification by a trusted supplier, the Toolex Taper Shank Reamer supports demanding machining tasks with consistent, high-quality results.
