Toolex Reamer - Straight Shank - Spiral Flute - Stub Length - Carbide - Through Coolant - H4 - 7.12mm

Toolex Reamer – Straight Shank – Spiral Flute – Stub Length – Carbide – Through Coolant – 7.12 mm is a precision finishing tool designed for through-coolant reaming in limited-space applications. With a 7.12 mm diameter, it delivers tight ISO H4 (D = ISO H4) hole sizes and clean finishes in a range of materials. This intermediate precision (k10) carbide reamer is suitable for engineers, machinists, and workshop operators who demand consistent hole quality in one pass.

Manufactured by Toolex Ltd, this reamer uses a straight shank for quick tool changes and compatibility with standard holders. It features left-hand spiral flutes and a right-hand cutting action, engineered to provide stable cutting, effective chip control, and reliable coolant delivery directly to the cutting edge through the through-coolant design.

• Through-coolant design: Delivers coolant right to the cutting edge and evacuates chips efficiently, helping maintain cutting efficiency and surface finish in demanding workpieces.
• Stub-length carbide construction: Provides enhanced rigidity and dimensional stability in confined bores, reducing deflection and improving hole roundness and accuracy.
• DIN 8093 with H4 tolerance: Ensures precise hole sizing and compatibility with standard reaming setups, delivering repeatable results across multiple jobs.

This reamer is a purpose-built finishing tool for through-coolant reaming tasks where tight tolerances and reliable performance matter most. It supports consistent results, reduces finishing rework, and integrates smoothly into established machining workflows.
