The Toolex Reamer is a straight-shank, spiral-flute finishing tool designed for precise hole enlarging and finishing in metalworking. Made from HSS-E (high-speed steel with cobalt), it delivers durability and heat resistance for repeatable, tight-tolerance holes across a range of materials. Diameter: 8.76 mm Shank type: Straight shank for compatibility with a wide range of toolholding systems Flute design: Spiral flute promotes efficient chip evacuation and reduces clogging Material: HSS-E (cobalt-enhanced high-speed steel) for wear resistance and heat tolerance Primary use: Precision hole enlargement and finishing with smooth bore quality Consistency: Known for accurate, repeatable results and tight tolerances The spiral flute and cobalt-enhanced steel work together to deliver clean, burr-free holes with a smooth surface finish, even in harder materials. The straight shank enables quick, stable clamping in standard toolholding setups, making it easy to integrate into existing machining cells. Ideal for finishing operations after drilling or prior to final assembly, this reamer maintains diameter accuracy across multiple passes and supports longer tool life in steels, cast irons, and other common metals.
