Toolex Taper Shank Reamer - HSS Spiral Flute Long Length (H5) - 17.07mm

The Toolex Taper Shank Reamer is an intermediate precision HSS (M2) long-series reamer designed for finishing deep holes to ISO H5 tolerance. It features a taper shank, left-hand spiral flute, and right-hand cutting for stable, predictable finishes in a single setup.

Manufactured to BS 328/4 by Toolex Ltd, this reamer is sized at 17.07 mm and is supplied on a made-to-order basis with a 24–48 hour despatch window. Please note that the “in stock” label refers to blanks available for immediate manufacture rather than a finished, ready-to-ship tool.

• Long-length taper shank for deep holes: Extended reach and added rigidity reduce chatter and deliver consistent bore finishes in deep workpieces.
• Left-hand spiral flute with right-hand cutting: Optimises chip evacuation and cutting action for a clean, controlled bore with each pass.
• ISO H5 tolerance (D) with BS 328/4 compliance: Ensures tight size control and reliable interchangeability with standard tooling, minimizing rework and setup time.

Using this reamer helps you achieve precise bore sizes with repeatable results, streamlines production by reducing rework, and provides a secure fit in compatible spindles thanks to the taper shank design. With clear lead times and order-driven manufacture, you can plan manufacturing runs around accurate despatch timing.
