The Toolex Reamer with a straight shank and spiral flute delivers precise 3.86 mm hole enlargement and finishing for metalworking projects. It’s built for machinists, fabricators, and shop professionals who demand dependable accuracy, smooth holes, and consistent performance.

• Diameter: 3.86 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
• Flute Design: Spiral flute for efficient chip evacuation and reduced loading during cutting
• Shank Type: Straight shank for broad compatibility with common tool holders and machining setups
• Precision: Designed to deliver tight tolerances and smooth hole finishes across multiple materials
• Applications: Ideal for precision hole enlargement and finishing in metalworking environments

By combining a spiral flute with cobalt-enhanced HSS, this reamer achieves efficient cutting action and better heat resistance, helping you maintain hole accuracy even on longer runs. The straight shank ensures easy clamping and compatibility with a variety of milling machines, drill presses, and CNC setups, giving you flexible integration in both manual and automated workflows. This makes the Toolex Reamer a reliable choice for refurbishing worn holes, fine-tuning diameters, and achieving clean, repeatable finishes in steel, aluminum, cast iron, and other common engineering materials.
