Toolex Reamer with a straight shank and spiral flute is a precision tool designed for engineers and machinists who need accurate hole enlargement and finishing. Forged in HSS-E (high-speed steel with cobalt), it combines durability with excellent heat resistance for reliable, repeatable results.

• Diameter: 4.17 mm (nominal)
• Material: HSS-E (high-speed steel with cobalt) for enhanced durability and heat resistance
• Flute design: Spiral flute for efficient chip evacuation and smoother cutting action
• Shank type: Straight shank for easy mounting in a wide range of tool-holding systems
• Function: Precision hole enlargement and finishing to achieve tight, consistent tolerances
• Performance: Known for accuracy and steady, repeatable results across a wide range of materials

This reamer is ideal for enlarging existing holes or achieving a precise diameter in projects that require clean, round holes. The straight shank offers compatibility with common drill presses, milling machines, and CNC setups, while the spiral flute design minimizes chip buildup and heat, helping extend tool life and maintain a smooth finish. Suitable for metals such as steel, aluminum, and cast iron, the Toolex reamer delivers dependable accuracy from prototype work to production runs.
