Frequently asked questions
The precision version has radial runout not exceeding 0.008 mm, while the standard version allows up to 0.015 mm. Nearly 2 times greater accuracy enables better machining quality and tighter dimensional tolerances.
It performs well in finish milling, precision reaming, injection mold machining, and the production of components with increased accuracy requirements. The 6 mm diameter is one of the most common cutting tool shank sizes.
The smallest ER11 measures 11.5×18 mm, the common ER16 measures 17×28 mm, the versatile ER20 measures 21×31 mm, the medium ER25 measures 26×34 mm, the large ER32 measures 33×40 mm, and the largest ER40 measures 41×46 mm. The system designation is marked on the collet body in accordance with DIN 6499.
