Designed for precision hole enlargement and finishing, the Toolex Reamer with a straight shank and spiral flute delivers consistent, smooth results in metalworking projects. It’s ideal for machinists and fabrication shops that demand tight tolerances and reliable performance.

• Diameter: 12.87 mm nominal size for accurate hole enlargement and finishing.
• Shank Type: Straight shank for broad compatibility with common toolholding systems.
• Flute Design: Spiral flute to promote efficient chip evacuation and cleaner hole walls.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance.
• Construction & Precision: Ground geometry and finish designed to deliver consistent hole sizes and smooth finishes across repetitions.
• Applications: Suitable for enlarging existing holes and achieving precise diameters in a wide range of materials, including steel and aluminum.

Using this reamer helps you achieve precise hole diameters with minimal finishing effort. The spiral flute reduces chip buildup and heat, extending tool life while maintaining hole quality. The cobalt-infused HSS-E construction provides durability under demanding cutting conditions, and the straight shank ensures quick, secure compatibility with diverse toolholding setups. Ideal for automotive assemblies, machinery housings, and general fabrication where repeatable, tight-tolerance holes are essential.
