Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 21.06mm

The Toolex Taper Shank Reamer is a long-length, M2 high-speed steel finishing tool designed to bring deep bores to ISO H5 tolerance using a BS 328/4 taper shank. With a 21.06 mm diameter, it’s built for precision bore finishing in metalworking and engineering projects.

Made from M2 high-speed steel, it features left-hand spiral flutes and right-hand cutting to optimize chip evacuation and maintain controlled, efficient material removal in long bore operations.

• Left-Hand Spiral Flute, Right-Hand Cutting: Enhances chip evacuation and delivers stable, smooth cutting in deep holes, reducing clogging and improving bore finish on demanding workpieces.
• ISO H5 Tolerance: Keeps bore sizes within tight, repeatable limits, minimizing rework and ensuring consistent results across batches.
• Long-Length Design: Provides extended reach for deeper bores while maintaining rigidity, reducing tool deflection and enabling accurate finishing in tall or long features.

The reamer helps you achieve precise, repeatable bore finishes with fewer passes, boosting throughput and reliability in production or workshop environments while aligning with standard taper shank tooling for easy integration into existing setups.
