The Toolex Reamer with straight shank and spiral flute is a precision tool designed for hole enlargement and finishing in metalworking. Crafted from HSS-E and sized at 12.31 mm, it delivers consistent, smooth holes with tight tolerances across a wide range of materials.

• Diameter: 12.31 mm nominal
• Material / Construction: HSS‑E (high‑speed steel with cobalt) for superior durability and heat resistance
• Flute Design: Spiral flute for efficient chip evacuation and cleaner cutting action
• Shank: Straight shank for reliable clamping in multiple tool holding systems
• Application: Precision hole enlargement and finishing for accurate results in various machining setups
• Accuracy: Consistent, tight tolerances and smooth hole finish across cycles

Designed for reliable performance, this reamer excels at enlarging drilled holes to a precise diameter while delivering a high-quality surface finish. The spiral flute promotes effective chip removal, reducing the risk of buildup that can hinder cutting efficiency. The straight shank provides broad compatibility with common tool holders and setups, enabling flexible use in different machines and fixturing. With its cobalt-enhanced HSS core, the Toolex reamer stands up to heat and wear, helping extend tool life in demanding reaming tasks. Ideal for engineers and machinists aiming for accurate holes, repeatable results, and efficient workflows across steel, aluminum, cast iron, and other common metals.
