Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 5.38mm

The Toolex Straight Shank Spiral Flute Stub Length Carbide Reamer, 5.38 mm, is a precision finishing tool designed to bring pre-drilled holes to exact size with repeatable accuracy. Built on an intermediate precision carbide (k10) substrate, it delivers reliable bore finishes across a range of materials while maintaining edge life through through coolant operation. The tool uses a left-hand spiral flute with right-hand cutting and adheres to DIN 8093 and ISO H4 tolerance standards, ensuring consistent results on every job.

This item is manufactured to order by Toolex Ltd and typically ships within 24–48 hours. Its stub-length design and straight shank deliver rigidity in tight spaces, supporting clean bore finishes and reliable performance through numerous finishing passes.

• Through-coolant design: Keeps cutting edges cooler, improves chip evacuation, and extends tool life for long production runs.
• Carbide substrate (k10) for durability: Resists wear and maintains accuracy for repeated reaming of challenging materials.
• DIN 8093 / ISO H4 precision with straight shank, stub length: Delivers tight bore sizes with consistent fits and straightforward setup in compact work envelopes.

With this reamer, you finish holes quickly and accurately, reducing rework and improving part-to-part consistency. The combination of carbide hardness, through-coolant flow, and precise tolerances helps you achieve reliable results across projects, from prototypes to production runs, with less downtime and more predictable outcomes.
