Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 21.12mm

The Toolex Taper Shank Reamer is a long-length, intermediate-precision HSS (M2) tool designed to finish deep holes with a 21.12 mm nominal diameter to ISO H5 tolerance. Its BS 328/4 taper shank fits standard toolholders for quick, confident setups, and it is manufactured to order to Toolex specifications for reliable results in production and workshop environments.

With an extended reach that maintains rigidity in deep bores, this reamer delivers consistent concentricity and a high-quality surface finish in hard-to-reach holes.

• Extended reach for deep bores: Long-Length taper shank design provides extended reach for deep holes while maintaining rigidity, ensuring consistent concentricity and finish in hard-to-reach holes.
• Efficient cutting and chip evacuation: Left-Hand Spiral Flute with Right-Hand Cutting enables efficient chip evacuation and smooth cutting action, helping achieve a clean bore with minimal finishing passes.
• ISO H5 accuracy with standard toolholder compatibility: HSS (M2) with ISO H5 tolerance (BS 328/4) combines wear resistance with tight size control, delivering reliable hole accuracy and easy compatibility with standard toolholders.

Using this reamer helps you achieve precise bore sizes with repeatable results, reducing rework and speeding up production cycles. The extended reach and stable taper shank improve setup reliability and surface finish, while the hard-wearing HSS core supports longer tool life in demanding reaming tasks. With its ISO H5 tolerance and standard taper shank compatibility, it integrates smoothly into existing tooling and workflows, making it a dependable choice for engineers, machinists, and workshops focused on precision and efficiency.
