Made from M2 high-speed steel and ground to ISO H5 tolerance (−0 to +0.005 mm), this standard-length reamer is ideal for intermediate-precision work in mechanical, automotive, and fabrication environments.

Designed with a BS 328/4 taper shank for secure seating, it uses a left-hand spiral flute with right-hand cutting to optimise chip control and surface finish. Supplied by Toolex Ltd, this item is manufactured to order with a 24–48 hour despatch window.

• ISO H5 tolerance (−0 to +0.005 mm): Ensures tight, repeatable bore sizes for reliable fits and minimal rework across batches.
• HSS M2 material: Provides wear resistance and long tool life, reducing the need for frequent replacements in busy shops.
• Taper shank with left-hand spiral flute: Secure mounting in compatible holders with efficient chip evacuation and a smooth, controlled cutting action for consistent finishing.

Using this reamer helps you achieve consistent bore quality, speeds up finishing operations, and supports easier assembly due to predictable hole sizes. The robust M2 HSS body, combined with ISO H5 control and BS 328/4 taper, gives you a durable tool you can rely on across multiple jobs, with clear manufacturing-to-order timing to plan your workflow.
