The Toolex Taper Shank Reamer delivers precise, repeatable bore finishing for tapered holes, with a 16.77 mm diameter. Made from HSS (M2) and designed as a long-series taper shank, it uses a left-hand spiral flute and right-hand cutting to control material removal and improve bore quality. Built to BS 328/4 and finished to ISO H5 tolerance (D), this reamer is supplied by Toolex Ltd and manufactured to order; please allow 24–48 hours for despatch.

• Long-series taper shank for stability: The extended taper shank provides rigid alignment in machines, reducing deflection and helping maintain a consistent hole size through longer bore travel.
• Left-hand spiral flute with right-hand cutting: This pairing improves chip evacuation and delivers a smoother bore finish with controlled material removal during reaming.
• ISO H5 tolerance (D) with BS 328/4 standard: Ensures consistent dimensions and reliable compatibility with tooling and assemblies.

Choosing this reamer supports reliable, repeatable hole sizing, reduces rework, and yields smoother finishes that improve downstream assembly and performance. The robust HSS construction is built for demanding reaming tasks, and the made-to-order production model helps ensure you receive the exact tool you need within a short despatch window.
