Toolex Reamer with straight shank and spiral flute is a precision tool built for accurate hole enlargement and finishing. It’s ideal for machinists and fabricators who need tight tolerances and smooth bore finishes in metalworking.

• Diameter: 4.22 mm, delivering a precise final bore size
• Material: HSS-E (high-speed steel with cobalt) for exceptional wear resistance and heat tolerance
• Flute Design: Spiral flute enables efficient chip evacuation and smoother cutting action
• Shank Type: Straight shank offers broad compatibility with common tool holding systems
• Accuracy: Consistent performance with tight tolerances across multiple passes
• Applications: Suitable for enlarging existing holes or achieving a specific diameter across a range of materials

The Toolex Reamer is engineered to enhance finishing quality and reliability in both manual and CNC setups. Its cobalt-enhanced HSS composition stands up to demanding cutting conditions, while the straight shank and spiral flute deliver predictable results with efficient chip removal. Use this reamer to achieve precise bore dimensions, improve hole roundness, and extend tool life in a variety of metalworking scenarios—from repair work to precision fabrication.
