Toolex Reamer, with a straight shank and spiral flute, is a precision tool designed for accurate hole enlargement and finishing in metalworking. Built with HSS-E (high-speed steel with cobalt), it delivers durable performance and consistent results across repeated uses. Diameter: 10.39 mm precision size for final hole sizing and reliable fit Shank type: Straight shank compatible with a wide range of toolholding systems Flute design: Spiral flute promotes efficient chip evacuation and a smoother cutting action Material: HSS-E (coated with cobalt) for improved heat resistance and wear longevity Applications: Ideal for precision hole enlargement and finishing across various materials With its combination of a straight shank, spiral-flute geometry, and cobalt-enhanced HSS construction, this reamer delivers consistent, burr-free holes and tight tolerances. The spiral flute design helps clear chips quickly, reducing heat buildup and extending tool life in higher-speed applications. Its straightforward shank attachment ensures easy integration into standard machining setups, making it a reliable choice for workshops and production environments that require precise hole sizing and high repeatability.
