Toolex Reamer with a straight shank and spiral flute delivers precise hole enlargement and smooth finishing, built for professional machinists and shop floors that demand consistent bore quality. Crafted in HSS‑E (high‑speed steel with cobalt) for durability and heat resistance, it maintains accuracy across tough materials.

• Diameter: 7.67 mm
• Shank: Straight shank compatible with common tool holding systems
• Flute Design: Spiral flute for efficient chip evacuation and reduced chip build‑up
• Material: HSS‑E (high‑speed steel with cobalt) for enhanced hardness and heat resistance
• Application: Precision hole enlargement and finishing across a wide range of materials

The spiral flute design improves cutting efficiency and chip clearance, helping to maintain bore geometry during both enlarging and finishing passes. The cobalt-enhanced HSS‑E construction offers improved wear resistance in demanding materials, contributing to longer tool life and more consistent performance. The straight shank provides reliable seating in multiple tool-holding systems, enabling flexible setups across different machines and fixtures. Use this reamer to enlarge existing holes to a precise 7.67 mm bore and achieve a smooth, true finish with tight tolerances.
