Meet the Toolex Reamer—a straight-shank, spiral-flute reaming tool designed for precise bore enlargement and finishing. Built for machinists and workshop professionals, this HSS-E reamer (3.79 mm) delivers reliable accuracy and clean holes across a range of materials.

• Diameter: 3.79 mm bore enlargement and finishing for tight tolerances
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Flute design: Spiral flute supports efficient chip evacuation and smoother cutting
• Shank type: Straight shank for easy clamping and broad compatibility with common tool-holding systems
• Precision: Consistent hole size and smooth bore finish across multiple passes
• Applications: Ideal for enlarging existing holes and achieving specific diameters in a variety of metals

This reamer helps you achieve precise diameters with minimal runout, improved surface finish, and predictable results. The spiral flute aids chip removal and cooling, reducing heat buildup and helping extend tool life in demanding operations. With its straightforward straight shank, setup is quick, and compatibility with different machines ensures flexible use in both stationary and CNC environments.
