Toolex Reamer with a straight shank and spiral flute is engineered for precision hole enlargement and finishing in metalworking environments. Made from HSS-E cobalt steel, it delivers durable, heat-resistant performance for demanding machining tasks.

• Diameter: 4.52 mm cutting diameter for precise bore sizing.
• Material: HSS-E (high-speed steel with cobalt) composition for exceptional wear resistance and heat tolerance.
• Flute design: Spiral flute optimizes chip evacuation and promotes smoother cutting action.
• Shank type: Straight shank compatible with a wide range of tool-holding systems.
• Precision performance: Consistent, accurate holes with tight tolerances.
• Versatility: Suitable for enlarging existing holes or achieving a specific bore diameter across many materials.
• Reliability: Delivers repeatable results across production runs.

The Toolex straight-shank spiral-flute reamer helps you improve bore quality and reduce rework. The spiral flute design minimizes chip buildup for cleaner cuts and steadier finishes, while the cobalt-infused HSS construction stands up to heat and wear in multi-pass finishing. With its straight shank, it integrates smoothly into common CNC and manual setups, giving you flexible, reliable performance for hole enlargement tasks at 4.52 mm. Ideal for workshop environments where precision bore sizes and consistent surface finish matter for critical fits and assemblies.
