Meet the Toolex Reamer—a straight-shank, spiral-flute reamer crafted for precision hole enlargement and finishing. Designed for machinists and shop technicians who demand consistent tolerances and smooth bore surfaces.

• Diameter: 4.10 mm
• Shank type: Straight shank for broad compatibility with common tool-holding systems (chucks, collets, and holders)
• Flute design: Spiral flute achieves efficient chip evacuation and reduces the risk of chip build-up during cuts
• Material: HSS-E (high-speed steel with cobalt) for superior hardness, heat resistance, and long tool life
• Accuracy: Consistent hole size with tight tolerances and a clean, smooth bore finish
• Applications: Ideal for precision hole enlargement and finishing across a range of metals including steels and non-ferrous alloys

With its robust HSS-E construction and spiral flute geometry, this reamer maintains stable performance under demanding cutting conditions, delivering precise, repeatable holes. The straight shank supports versatile mounting in various machine setups, making it a reliable choice for finishing operations that require exact dimensions and excellent surface quality. Use it to enlarge existing holes to a defined diameter and achieve a clean, burr-free bore that accommodates fasteners, bushings, or mating components with confidence.
