The Toolex Reamer with a straight shank and spiral flute is a precision tool designed for machinists who need reliable, smooth hole enlargement and finishing. Built from HSS-E, it delivers durable performance and excellent heat resistance for demanding metalworking tasks, with a precise 4.99 mm diameter for tight tolerances.

• Diameter: 4.99 mm reamer for accurate hole enlargement and finishing within tight tolerances.
• Material: HSS-E (high-speed steel with cobalt) offering superior hardness and heat resistance under cutting pressures.
• Flute Design: Spiral flute promotes efficient chip evacuation and steadier cutting action.
• Shank Type: Straight shank for easy mounting in a wide range of tool holders and collets.
• Precision Performance: Known for consistent accuracy and smooth hole finishes across multiple materials.

Designed to enlarge existing holes cleanly or achieve a specific final diameter, this reamer minimizes secondary finishing passes and delivers repeatable results for production runs or prototype work. The spiral flute reduces chip buildup and heat, while the straight shank ensures compatibility with most machining setups, giving you flexible, dependable performance in metalworking projects.
