The Toolex Reamer with a straight shank and spiral flute is a precision finishing tool designed for accurate hole enlargement and finishing. Sized at 7.90 mm, it’s ideal for machinists and workshops seeking repeatable, clean-hole results across a variety of metals.

• Diameter: 7.90 mm for precise hole enlargement and controlled finish
• Material: HSS‑E (high‑speed steel with cobalt) for enhanced hardness and heat resistance
• Flute Design: Spiral flute promotes efficient chip evacuation and smoother cutting action
• Shank Style: Straight shank offers broad compatibility with most tool holding systems
• Application: Finishing and enlarging holes to tight tolerances with consistent results

This reamer’s cobalt-enhanced HSS construction maintains a sharp cutting edge under higher temperatures, extending tool life and delivering stable hole sizes. The spiral flute accelerates chip removal, reducing the risk of chip buildup that can affect accuracy and surface finish. The straight shank simplifies mounting in standard collets, chucks, or adapters, making it easy to integrate into existing machining setups. Ideal for a range of materials—from steel and cast iron to aluminum and stainless steel—this reamer provides reliable performance for deburring, fine finishing, and precise diameter control in both manual and CNC operations.
