It is a manufactured-to-order item, with a 24–48 hour despatch window.

• Left-hand spiral flute with right-hand cutting: Promotes efficient chip removal and smooth cutting action, reducing pulling and chatter in deep bores.
• Super-long HSS taper shank (M2): Provides extended reach for deep or hard‑to‑access holes while maintaining rigidity and accuracy across the length.
• ISO H5 tolerance on a BS 328/4 taper: Delivers precise sizing and reliable interchange in standard tooling setups for repeatable results.

This reamer is built for professional workshops and demanding fabrication work where consistent, precise hole finishing matters. By combining a robust M2 high-speed steel core with a long, stable taper shank and a geometry engineered for deep reaming, it helps you reduce pass-through attempts, improve hole quality, and keep production moving smoothly.
