The Toolex Reamer with a straight shank and spiral flute is a precision tool designed for accurate hole enlargement and finishing in metalworking. It’s ideal for machinists and shops seeking tight tolerances and smooth bore finishes, offering durability and broad toolholding compatibility.

• Diameter: 3.17 mm
• Material: HSS‑E (high‑speed steel with cobalt) for enhanced hardness and heat resistance
• Flute Design: Spiral flute for efficient chip evacuation and stable cutting
• Shank: Straight shank compatible with a wide range of toolholding systems
• Precision: Delivers consistent hole sizes with tight tolerances and smooth finishes
• Applications: Suitable for enlarging and finishing holes in steel, aluminum, and other alloys

This reamer provides reliable, repeatable results across a variety of machining setups. The spiral flute efficiently evacuates chips, helping to reduce heat buildup and prevent clogging, which yields cleaner bore surfaces with fewer finishing passes. The straight shank enables quick, hassle-free tool changes and broad compatibility with common chucks and collet systems, while the HSS‑E composition extends tool life in demanding materials. Whether preparing housings, fixtures, or precision components, this reamer helps you achieve accurate diameters, smooth surfaces, and consistent assemblies.
