Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 8.39mm

The Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 8.39mm is an intermediate precision carbide reamer designed for finishing pre-bored holes to exact size. With a straight shank and stub length, it’s built for tight-tool setups where space is limited. The left-hand spiral flute and right-hand cutting direction, combined with through coolant, deliver a clean, accurate bore in challenging materials.

Supplied by Toolex Ltd, this reamer adheres to DIN 8093 and delivers an ISO H4 tolerance, ensuring consistent hole size across production runs. The tool is manufactured to order, with despatch typically in 24–48 hours. The 8.39 mm diameter and stub-length form, along with the through-coolant design, help maintain rigidity and accuracy in restricted spaces.

• Left-hand spiral flute with through coolant: Efficient chip evacuation and smooth bore quality in tight or deep holes.
• Carbide construction (k10) for durability: Longer tool life and stable performance in demanding reaming applications, reducing tool changes.
• DIN 8093 / ISO H4 tolerance: Precise, repeatable hole sizes that support reliable assembly and consistent results.

This reamer helps you finish holes to exact size with repeatable accuracy, reducing finishing time and scrap. The through coolant design keeps cutting zones cooler and cleaner, while the stub-length, straight-shank geometry fits tight setups without sacrificing rigidity. With Toolex’s DIN 8093 compatibility and H4 tolerance, you can rely on consistent performance across production runs and precision work alike.
