Toolex Reamer - Stub Type - Spiral Flute - Straight Shank - HSS-E - H4 - 7.16mm

The Toolex Stub Reamer, 7.16 mm, is an intermediate-precision finishing tool designed to produce accurate, smooth holes in tough materials. Built from HSS-E (M35 cobalt), it delivers improved wear resistance and longer cutting life for repeat production.

The reamer uses a left-hand spiral flute with right-hand cutting (DIN 8089) to deliver controlled chip evacuation and consistent bore finishes. With ISO H4 tolerance under DIN 8089, it maintains a precise 7.16 mm bore every time, ensuring repeatable results across components. Manufactured to order by Toolex Ltd, despatch is typically 24–48 hours.

• HSS‑E alloy for longer tool life: The HSS-E (M35 cobalt) composition provides superior wear resistance and cutting performance in hard materials, helping the reamer stay sharper longer and reducing tool changes.
• Left-hand spiral flute with right-hand cutting: This flute orientation improves chip control and cutting action, delivering a clean bore and stable operation even in demanding jobs.
• ISO H4 tolerance for a precise 7.16 mm bore: Ensures tight, repeatable hole sizes across components, enabling reliable fits and high part interchangeability in production runs.

Using this reamer in your workflow delivers precise, smooth bore finishes with tight tolerances, reducing post-machining rework and speeding assembly. The durable HSS‑E edges and DIN 8089-compliant design support reliable, repeatable results across batches, helping you plan production with confidence.
