Engineered for precision hole finishing, the Toolex Reamer — Straight Shank, Spiral Flute, HSS-E — delivers consistent bore quality at a 4.59 mm diameter. With a straight shank and spiral flute, it fits a wide range of tool-holding systems and cutting conditions.

• Diameter: 4.59 mm for precise hole enlargement and finishing to tight tolerances
• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
• Flute Design: Spiral flute for efficient chip evacuation and smoother cutting action
• Shank Type: Straight shank ensures broad compatibility with various tool holders and machining setups
• Applications: Ideal for enlarging existing holes and achieving accurate diameters across a range of materials

This reamer delivers reliable, repeatable results by combining the durability of cobalt-enhanced HSS with a flute geometry that promotes clean cuts and steady bore quality. Its straight shank design provides flexible integration into different machines and fixturing, making it a practical choice for production runs or meticulous finishing work. Use for precise bore sizing, deburring, and finishing operations where bore concentricity and surface smoothness matter, and pair with appropriate lubrication and conservative speeds to maximize tool life and finish quality.
