Toolex Reamer with a straight shank and spiral flute is your reliable solution for precision hole enlargement and finishing in metalworking. Designed for machinists who demand repeatable, tight tolerances, this HSS-E cobalt reamer delivers consistent bore quality across a range of materials.

• Diameter: 2.51 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance
• Flute Design: Spiral flute for efficient chip evacuation and smoother cutting
• Shank Type: Straight shank for easy clamping in common toolholding systems
• Applications: Precision hole enlargement and finishing to achieve accurate final diameters

With its durable HSS-E cobalt construction, this reamer resists wear and heat during extended cutting passes, helping maintain hole size and surface finish. The spiral flute design minimizes chip buildup, boosting cutting efficiency and reducing the risk of clogging in deeper bores. The straight shank offers broad compatibility with drill chucks, collets, and other toolholding setups, providing flexible integration into milling machines, lathes, or CNC workflows. Ideal for enlarging existing holes or achieving a precise final diameter, this reamer supports clean, accurate bores and repeatable results across a variety of materials and applications.
