Toolex Reamer – a straight shank, spiral flute tool designed for precision hole enlargement and finishing. Sized at 5.69 mm and built from HSS-E, it delivers durable, heat-resistant performance across a range of materials and machining setups.

• Diameter: 5.69 mm
• Shank: Straight shank for broad toolholding compatibility
• Flute Style: Spiral flute promotes efficient chip evacuation
• Material: HSS-E (high-speed steel with cobalt) for durability and heat resistance
• Application: Precision hole enlargement and finishing with consistent results
• Performance: Delivers smooth bore finishes and tight tolerances

This reamer stabilizes hole quality across a range of materials, from soft alloys to hardened steels, by maintaining a clean cutting environment and reducing heat build-up. The spiral flute minimizes chip buildup, lowering the chance of burrs and chatter while enabling stable passes in both CNC and manual setups. The straight shank simplifies integration with most toolholding systems, allowing quick changes in milling and drilling stations. Use it to enlarge existing bores or finish bore diameters to a precise size, achieving repeatable, smooth holes that reduce secondary finishing time and improve part-to-part consistency.
