Toolex Reamer - Taper Shank - Spiral Flute - Standard Length - HSS - H5 - 37.70 mm

The Toolex Reamer is an intermediate precision HSS taper-shank reamer designed to deliver finish-hole accuracy in machining and assembly tasks. Its left-hand spiral flute and right-hand cutting provide predictable cutting action and clean, burr-free finishes across a range of materials.

Manufactured to BS 328/4 standards by Toolex Ltd, this tool relies on M2 high-speed steel and ISO H5 tolerance (−0 to +0.005 mm) to hold precise hole sizes. It is made to order, with a 24–48 hour despatch window to ensure you receive a fresh, accurately ground component when you need it.

• Left-hand spiral flute with right-hand cutting: Delivers efficient chip evacuation and stable cutting action for consistent hole finishes and longer tool life.
• ISO H5 tolerance (−0 to +0.005 mm): Keeps holes within tight size limits, reducing overruns and the need for rework.
• Taper shank for secure alignment in standard toolholders: Ensures repeatable seating and low runout in common setups, improving surface finish and reliability.

This reamer helps you finish holes accurately on the first pass, improving workflow efficiency and overall machining reliability. By combining stable cutting, precise sizing, and dependable alignment, it supports higher quality results with less downtime and easier setup across a range of projects.
