The Toolex Reamer with a straight shank and spiral flute is a precision tool designed for machinists who need to enlarge or finish holes with tight tolerances. Crafted in HSS-E, it combines exceptional durability with heat resistance for reliable performance across a wide range of materials. Diameter: 10.47 mm Shank: Straight shank compatible with multiple tool-holding systems Flute Design: Spiral flute for efficient chip evacuation and smoother cutting Material: HSS-E (high-speed steel with cobalt) for extended tool life and heat resistance Application: Precision hole enlarging and finishing with consistent accuracy Performance: Delivers precise, smooth bores with tight tolerances across a wide range of materials The reamer excels at producing clean, accurate holes when existing diameters need to be nudged to a specific size. Its spiral flute minimizes chip buildup, improving cutting efficiency and reducing the risk of clogging during longer or more demanding passes. The straight shank design ensures straightforward integration with a variety of machine setups, while HSS-E construction offers reliable performance under heat-generating cutting conditions. Ideal for production or prototype work, this Toolex reamer helps you achieve repeatable bore finishes and tight tolerances across metals and other machinable materials.
