Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 18.43mm

The Toolex Reamer is a straight-shank, stub-length carbide reamer designed for through-holes, delivering precise bore finishes in a variety of materials. Its left-hand spiral flute and right-hand cutting, combined with through-coolant, provide reliable chip control and consistent hole quality in production runs.

Diameter: 18.43 mm with ISO H4 tolerance per DIN 8093. This intermediate precision (k10) carbide tool is supplied by Toolex Ltd and manufactured to order, with a despatch window of 24/48 hours.

• Carbide (k10) construction: Hard, wear-resistant cutting edge for longer tool life and stable, repeatable reaming performance even in tougher materials.
• Through‑coolant design: Coolant flows through the shank to the cutting edge, improving chip evacuation, reducing heat, and helping maintain hole accuracy in through-holes.
• DIN 8093 ISO H4 tolerance: Tight size control (18.43 mm) ensures reliable fits and consistent results across multiple parts and runs.

This reamer combines rigidity from the straight shank with the efficient cutting action of a stub-length carbide tool, delivering accurate bore finishes with minimal rework. Plan for production to account for its made‑to‑order status and you’ll gain predictable lead times and repeatable performance in your machining workflow.
