This is a spring collet according to the German DIN 6499 standard. The runout accuracy is ±15 microns to ±20 microns, but it is inexpensive.
This is an ER collet that conforms to the DIN 6499 standard. The accuracy is at a standard level. While Japanese-made ER spring collets have runout accuracy of ±0.003 mm to ±0.005 mm, the Fasttech ER spring collets have a runout accuracy of ±0.015 mm to ±0.020 mm. Even so, they are more precise than drill chucks and can securely hold drills. This is a user-friendly ER spring collet that prioritizes low cost over high standards of runout accuracy.
