• Taper Shank for Secure Mounting: A stable interface in collets and chucks reduces runout, delivering repeatable hole sizes in every pass.
• ISO H5 Tolerance on 30.21 mm Diameter: -0 to +0.005 mm tolerance ensures consistent bore diameters and less rework across production runs.
• Left-Hand Spiral Flute with Right-Hand Cutting: Optimizes chip evacuation and surface finish for smoother bores and reliable cutting action.

This reamer delivers precise, repeatable bore finishes with minimal rework, while the tapered shank ensures secure seating in standard tooling. The M2 HSS construction provides good wear resistance for longer life in common machining conditions, helping you maintain quality across parts and batches. The clear manufacturing-to-order lead time supports planning and scheduling in job shops and production environments.
