• ISO H5 tolerance (D = -0 to +0.005 mm): Delivers consistent bore sizes for reliable, repeatable hole finishing across parts.
• Left-hand spiral flute with right-hand cutting: Optimizes material removal and chip clearance for a smoother bore finish.
• Taper shank in standard length: Provides secure fit in standard toolholders and straightforward setup on compatible machines (BS 328/4).

This reamer helps you achieve precise bore diameters with predictable results, reducing finishing steps and rework. The M2 HSS construction offers durability for repeated use, while the taper shank and standard-length design ensure easy integration into existing tooling setups. Manufactured to order, it aligns with typical workshop workflows without sacrificing accuracy or reliability.
