The Toolex Reamer with straight shank and spiral flute is engineered for precision hole enlargement and finishing in metalworking, delivering consistent bore quality for professional machinists and shops.

• Diameter: 8.47 mm — targeted final hole size for accurate bore finishing
• Flute design: Spiral flute for efficient chip evacuation, reducing chip buildup and improving cutting performance
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and superior heat resistance
• Shank type: Straight shank compatible with a wide range of toolholding systems for flexible setup
• Application: Precision hole enlargement and finishing across a variety of machinable materials
• Accuracy: Consistent performance that yields tight tolerances and a smooth bore finish

With this reamer, you’ll achieve cleaner, more reliable holes in fewer passes, helping to reduce cycle times and post-process finishing. The cobalt-enriched HSS-E construction stands up to cutting heat, extending tool life while maintaining diameter stability under load. The straight shank simplifies integration with common chucks and collets, enabling quick changes and stable alignment in your existing setup. The spiral flute design enhances chip evacuation, minimizing the risk of clogging and chatter so you get precise, repeatable hole sizes every time.
