Toolex Reamers deliver precise, clean hole enlargements with a reliable straight-shank design, built for precision machining. Ideal for professional shops and skilled hobbyists, these HSS-E reamers deliver consistent finishes and tight tolerances across a range of metals.

• Diameter: 3.51 mm bore size for accurate enlargement and finishing.
• Shank Type: Straight shank for easy clamping in common tool-holding systems.
• Flute Design: Spiral flute for efficient chip evacuation and reduced risk of clogging.
• Material: HSS-E (high-speed steel with cobalt) for superior heat resistance and longevity.
• Accuracy & Finish: Delivers repeatable, smooth holes with tight tolerances suitable for precision work.

Using the Toolex 3.51 mm spiral-flute reamer helps you enlarge pre-drilled holes or achieve a precise final diameter with a high-quality surface finish. The cobalt-enhanced steel maintains sharpness through multiple passes, while the spiral flute minimizes chip buildup and heat, supporting longer tool life and steadier cuts. Its straightforward, compatible shank design makes it a versatile choice for a wide range of machining setups, from standard drilling rigs to CNC mills, in materials such as steel, aluminum, and other common metals. Whether you’re finishing a bore to a specific size or bringing an oversized hole to spec, this reamer provides reliable performance you can count on.
