Toolex Reamer with a straight shank and spiral flute is a precision tool designed for accurate hole enlargement and finishing in metalworking. The 12.45 mm diameter, crafted from HSS-E cobalt, delivers durable, heat-resistant performance across a broad range of materials and machining setups.

• Diameter: 12.45 mm
• Shank: Straight shank compatible with most tool-holding systems
• Flute design: Spiral flute for efficient chip evacuation and smoother cutting
• Material: HSS-E (high-speed steel with cobalt) for increased hardness and heat resistance
• Precision: Delivers consistent hole enlargement and a smooth finish with tight tolerances

This reamer is ideal for anyone performing hole finishing in CNC mills, drill presses, or manual machines. The spiral flute aids chip removal, reducing the risk of buildup that can affect hole quality, while the straight shank ensures secure, repeatable clamping in diverse tooling setups. The combination of cobalt-enhanced HSS provides longevity under higher cutting temperatures, making it suitable for a variety of metals such as steel, cast iron, aluminum, and more. Use this tool to enlarge existing holes or achieve a precise final diameter with dependable, repeatable results—reducing rework and improving overall part fit and finish.
