Toolex Carbide Taper Shank Intermediate Reamer H5 21.42mm

The Toolex carbide taper shank intermediate reamer (21.42 mm) is a precision finishing tool designed to create accurate, smooth holes in metalwork. With a carbide tipped insert (K10), it delivers long life between changes, making it ideal for engineers, machinists, and workshop teams who require reliable bore finishes. This item is manufactured to order, so please allow 24–48 hours for despatch.

The reamer features a left-hand spiral flute and right-hand cutting for efficient chip evacuation and stable cutting performance. It uses a DIN 8051 B taper shank and ISO H5 tolerance, providing a secure fit in standard tool holders and ensuring repeatable bore sizes across production runs.

• Carbide-tipped design (K10): Delivers exceptional wear resistance and maintains precise bore dimensions, reducing tool changes and improving overall finishing consistency.
• DIN 8051 B taper shank with ISO H5 tolerance: Ensures a secure, reliable fit in common tooling setups while delivering repeatable, tight bore sizes.
• Left-hand spiral flute with right-hand cutting: Balances cutting forces for smoother operation, improves chip evacuation, and helps produce cleaner holes with minimal burrs.

Using this reamer helps you achieve consistent, high-quality bore finishes with fewer rework cycles and less downtime. The rugged carbide tip supports demanding materials, while the standardized taper shank and precision tolerances ensure compatibility with existing equipment, helping you speed setup and maintain steady throughput across production runs.
