Toolex Reamer, Straight Shank, Spiral Flute, HSS-E, 8.73 mm diameter, is a precision tool designed for accurate hole enlargement and fine finishing in machining applications. Built for shop professionals, it delivers consistent hole size and a clean surface finish across a range of materials.

• Diameter: 8.73 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
• Flute Design: Spiral flute for efficient chip evacuation and smoother cutting
• Shank Type: Straight shank provides secure clamping and broad compatibility with common tool holders
• Finish/Geometry: Precision-ground geometry to deliver tight tolerances and consistent bore quality
• Applications: Enlarge existing holes and finish bore to precise diameter across a wide range of materials and applications

By using this reamer, you get true, cylindrical holes with precise diameters and improved surface finish. The spiral flute reduces chip buildup, lowering the risk of binding and heat accumulation. The cobalt content and HSS-E construction extend tool life under demanding machining conditions. The straight shank enables quick setup across standard toolholding systems, increasing productivity in hole enlargement and finishing tasks. Ideal for finishing pre-drilled holes in steel, cast iron, aluminum, and other commonly machined materials, it helps reduce finishing passes and achieve consistent tolerances.
