The Toolex Reamer with a straight shank and spiral flute is a precision tool designed for accurate hole enlargement and finishing in metalworking, ideal for machinists and job shops seeking reliable, repeatable results. Crafted from HSS-E, it delivers strong durability and heat resistance to handle demanding materials and long production runs.

• Diameter: 12.42 mm
• Material: HSS-E (high-speed steel with cobalt) for enhanced wear resistance and heat tolerance
• Flute Design: Spiral flute promotes efficient chip evacuation and smoother cutting
• Shank Type: Straight shank provides broad compatibility with common tool holders and setups
• Applications: Precision hole enlargement and finishing across a variety of metals and alloys
• Performance: Consistent accuracy and clean hole finishes with dependable repeatability

By delivering precise diameter control and a smooth, burr-free finish, this reamer minimizes secondary finishing work and helps you achieve high-quality part surfaces. The spiral flute design reduces chip buildup and heat, extending tool life, while the straight shank ensures quick, secure seating in standard collets and chucks. Suitable for steel, cast iron, stainless steel, and non-ferrous materials, it’s a versatile choice for both new hole sizing and refining existing holes, enabling tighter tolerances and repeatable results across production runs.
