1.46mm (.0575") Carbide Spiral Reamer – 4 Flute – 3mm Shank – Hertel USA K026

This 1.46mm (.0575") solid carbide spiral reamer from Hertel is designed for precision hole finishing where tight tolerances and excellent surface finish are required.

Manufactured in the United States from high-quality micrograin carbide, this 4-flute spiral reamer provides smooth cutting action and superior chip evacuation compared to straight flute designs.

Carbide reamers are commonly used in CNC machining applications where consistent hole size, accuracy, and surface finish are critical. The spiral flute geometry helps reduce chatter and improves chip removal during the reaming process.
