Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 6.78mm

The Toolex Reamer, Straight Shank, Spiral Flute, Stub Length carbide reamer in 6.78 mm diameter is designed for through-coolant hole finishing to DIN 8093 with ISO H4 tolerance. Supplied by Toolex Ltd and manufactured to order, it typically ships within 24–48 hours, ensuring you can plan production with reliable lead times.

This intermediate precision carbide (k10) reamer features a left-hand spiral flute and right-hand cutting, optimized for through-coolant operations. Its stub-length design concentrates cutting action in shallow bores, helping you achieve precise bore sizes consistently across applications.

• Carbide k10 intermediate-precision grade: Delivers a durable, stable cutting edge with predictable wear, helping maintain accurate bore sizes over multiple reaming cycles.
• Through-coolant design: Enables coolant to reach the cutting zone and evacuate chips, promoting cooler, cleaner finishes and reducing the risk of built-up material in the hole.
• DIN 8093 / ISO H4 tolerance: Ensures tight size control and compatibility with mating parts, supporting reliable assembly and reduced secondary finishing.

Using this Toolex reamer helps streamline finishing operations, improves hole quality on first pass, and supports consistent results in production environments. The combination of stub-length geometry, through coolant, and precise tolerance makes it a dependable choice for demanding reaming tasks where accuracy and repeatability matter.
