Toolex Reamer with a straight shank and spiral flute is designed for precise hole enlargement and finishing in a wide range of materials. Built for professional use, this HSS-E reamer delivers durable performance and reliable, repeatable results in demanding machining setups. Diameter: Ø5.49 mm for accurate, incremental hole finishing and final size control Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance Flute Design: Spiral flute promotes efficient chip evacuation and cleaner cuts Shank: Straight shank provides compatibility with standard tool-holding systems and stable clamping Precision: Consistent hole size with tight tolerances and smooth bore finish Applications: Ideal for enlarging or finishing holes in steels, cast irons, and non-ferrous metals Whether you're enlarging an existing bore or achieving a precise final diameter, the Toolex Reamer delivers dependable performance. The straight shank ensures solid grip in CNC and manual machines, while the cobalt-infused HSS base withstands higher cutting temperatures. The spiral flute geometry enhances chip clearance, reducing clogging and improving cutting efficiency for a clean, accurate bore in a single or reduced-pass operation.
