Toolex Reamer with Straight Shank and Spiral Flute is a precision finishing tool designed for professionals who need accurate hole enlargement and smooth bore finishes. Built from HSS-E, it combines durability with excellent heat resistance to tackle a wide range of metals and alloys.

• Diameter: 3.87 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat tolerance
• Flute design: Spiral flute for efficient chip evacuation and reduced risk of clogging
• Shank: Straight shank provides broad compatibility with multiple tool holding systems
• Precision: Delivers consistent hole sizes with a smooth bore and tight tolerances
• Applications: Ideal for enlarging existing holes or achieving a specific diameter across a wide range of materials

With its cobalt-infused HSS construction, this reamer maintains cutting effectiveness under heat, extending tool life and delivering repeatable results. The spiral flute keeps chips moving away from the cutting edge, improving cutting efficiency and reducing the chance of material build-up that can affect accuracy. The straight shank design ensures easy mounting in standard collets, chucks, and holders, making it a versatile choice for both CNC and manual machining setups. Whether refining a drilled hole to a precise diameter or finishing a bore to the exact tolerance, the Toolex Reamer offers reliable performance for precise, professional results.
