The Toolex Reamer with straight shank and spiral flute is a precision hole finishing tool designed to enlarge and finish holes with tight tolerances. Built from HSS-E cobalt and configured for a 12.53 mm diameter, it’s ideal for machinists seeking consistent bore quality across common metals.

• Diameter: 12.53 mm
• Material: HSS-E cobalt steel for enhanced wear resistance and heat tolerance
• Flute design: Spiral flute for efficient chip evacuation and smoother cutting
• Shank: Straight shank for broad compatibility with tool holders and collets
• Applications: Precision hole enlargement and finishing across a range of machining materials
• Performance: Maintains accurate tolerances with a consistent surface finish

In practice, the spiral flute promotes efficient chip removal, helping to prevent chip build-up and overheating during deeper reams. The HSS-E composition resists wear and sustains sharpness under demanding cutting conditions, delivering repeatable hole quality across multiple runs. The straight shank design ensures stable clamping in common tool-holding systems, enabling flexible setups and reproducible results on various machines. Use this reamer to enlarge existing holes or achieve a precise final diameter, delivering smooth, burr-free bores in steel, aluminum, and other alloys.
