Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 21.58mm

The Toolex Taper Shank Reamer is an intermediate-precision HSS long-length tool designed to finish bores that use taper shanks. Built to BS 328/4 standards with a left-hand spiral flute and right-hand cutting, it delivers consistent bore sizes and smooth finishes for deep-hole work. Sized at 21.58 mm diameter, it suits engineers, machinists and hobbyists who demand reliable performance in deep, precisely sized holes.

Manufactured to order by Toolex Ltd, this reamer offers ISO H5 tolerances on a BS 328/4 taper shank, ensuring repeatable bore sizes and compatibility with standard taper shank holders and common tooling setups. The long-length design provides extended reach for deep bores while maintaining rigidity, reducing the need for multiple passes and setup changes.

• Long-Length Design: Extended reach for deep bores reduces the need for multiple passes while preserving rigidity for clean, accurate finishes.
• Left-Hand Spiral Flute with Right-Hand Cutting: Promotes efficient chip evacuation and stable cutting, helping you achieve consistent bores in longer holes.
• ISO H5 Tolerance on BS 328/4 Taper Shank: Delivers repeatable bore sizes with tight control and easy compatibility with standard taper shank tooling ecosystems.

Together, these features deliver precise, reliable reaming for deep, taper-shank bores with fewer passes and less rework, helping you maintain steady workflow and confident bore quality across projects.
