Toolex Reamer - Stub Type - Spiral Flute - Straight Shank - HSS-E - H4 - 7.50mm

The Toolex 7.50 mm HSS-E stub reamer is a precision finishing tool designed to bring holes to exact size with repeatable accuracy. Built for engineers, machinists, and workshops that demand reliable, clean hole finishes, this reamer uses HSS-E (M35 cobalt) for superior wear resistance and longer tool life.

Its stub form provides rigidity in tight bores, while the left-hand spiral flute and right-hand cutting deliver controlled material removal for predictable results. Manufactured to order by Toolex Ltd., despatch is 24–48 hours. It adheres to DIN 8089 and delivers ISO H4 tolerance to ensure consistent hole size at 7.50 mm, supporting reliable fits in precision assemblies.

• Rigid stub design for tight bores: The stub geometry provides excellent rigidity in restricted holes, minimizing deflection and delivering stable, repeatable finishes in small-diameter reaming tasks.
• HSS‑E cobalt for longer life: M35 cobalt content enhances wear resistance, enabling more finishing passes before sharpening and extending tool life in challenging materials.
• DIN 8089 / ISO H4 size control: Tight, standard-compliant tolerances ensure the hole remains at 7.50 mm with repeatable finishes, reducing rework and improving part-to-part consistency.

This reamer helps you achieve precise 7.50 mm holes with dependable, repeatable results, improving workflow and reducing downtime in production or precision assembly work. The combination of robust HSS‑E material, rigid stub geometry, and standard tolerances makes it a reliable choice for professional shops and demanding projects alike.
