Toolex Reamer with a straight shank and spiral flute delivers precise hole enlargement and finishing for machinists who demand reliable, consistent bore quality. Built from HSS-E, it combines durability and heat resistance to tackle demanding metalworking tasks across a range of setups.

• Diameter: 4.54 mm
• Shank: Straight shank design for easy clamping in collets, end mill holders, and common toolholding systems
• Flute design: Spiral flute provides efficient chip evacuation and smoother cutting, reducing chip buildup
• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
• Applications: Precision hole enlargement and finishing with tight tolerances across a variety of metals

This reamer is engineered to deliver a clean, accurate bore with minimal finishing work. The cobalt-infused HSS-E construction stands up to higher cutting temperatures, extending tool life on longer runs, while the spiral flute design improves chip removal to maintain steady cutting performance and reduce heat. The straight shank ensures broad compatibility with a wide range of milling machines, drill presses, and CNC setups, making it a dependable choice for workshops that value precision and versatility.
