Toolex Reamer with a straight shank and spiral flute is designed for precision hole enlargement and finishing, ideal for machinists and shops that demand consistent, smooth holes with tight tolerances.

• Diameter: 6.58 mm nominal for accurate sizing during bore finishing
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Flute design: Spiral flute promotes efficient chip evacuation and reduces risk of chip buildup
• Shank: Straight shank offers broad compatibility with common tool-holding systems
• Precision: Delivers repeatable hole sizes and smooth bore finishes across passes
• Applications: Ideal for enlarging pre-drilled holes and achieving tight tolerances in a wide range of materials

By combining cobalt-enriched HSS with a spiral flute, this reamer maintains cutting efficiency under heat and heavy use, extending tool life. The spiral design ensures steady chip flow, minimizing chatter and enabling cleaner, more accurate bore surfaces. The straightforward straight shank simplifies setup across CNC mills, drill presses, and other tooling configurations, delivering reliable seating and quick changes. Use the 6.58 mm Toolex Reamer to transition from a pilot hole to a finished bore with high dimensional accuracy, reducing rework and improving part quality across metalworking applications.
