Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 19.16mm

The Toolex Taper Shank Reamer is an intermediate-precision, long-length HSS finishing tool designed to resize and refine deep internal bores with tight control. Made from M2 high-speed steel, this taper-shank reamer features left-hand spiral flutes and right-hand cutting for predictable material removal and smooth bore finishes. Supplied by Toolex Ltd to BS 328/4 standards, it’s a reliable choice for engineers, machine shops, tradespeople, and hobbyists who demand accurate, repeatable bore sizing.

Nominal diameter 19.16 mm with ISO H5 tolerance (D = H5) ensures a precise bore that supports proper fits and assemblies. This reamer is manufactured to order, with an expected despatch window of 24–48 hours, providing a controlled lead time for quality, made-to-order tooling.

• ISO H5 tolerance for precise bores: Delivers consistent hole sizes that mate reliably with components and assemblies.
• Long-length M2 HSS with left-hand spiral flute and right-hand cutting: Enables deep-hole finishing, efficient chip evacuation, and a stable, predictable cut for a clean bore finish.
• Taper shank (BS 328/4) for secure mounting: Fits standard tooling holders with reduced runout, boosting stability and dimensional accuracy during use.

Using this reamer helps you achieve repeatable bore precision, reduces finishing passes, and extends tool life thanks to robust HSS construction. The long reach of the flute combined with a secure taper shank makes it well suited to both production environments and detailed fabrication work, delivering reliable results with every job.
