Concentricity：
highly polished surface
type, layout and number of slots optimised
blue ring as mark of quality
8° master gauge for collet chucks and collets is the same - no tolerance!
FAHRION is the only manufacturer with a concentricity of ≤ 2µm for ER Collets |
| Comparison Fahrion – Regofix: | |
| FAHRION | REGOFIX |
| Standard grade GER-B with 5 µm run out | Standard grade ER Standard with 10 µm run out |
| High precision grade GER-HP with 2 µm run out | High precision grade ER-UP with 5 µm run out |
Concentricity measured between holder taper and collet closing taper ≤1µm

highly polished surface
Precision Collet Chuck designed to clamp nominal diameter only
| collet chuck and clamping nut with trapezoidal thread and two cylindrical guides form a unit All these innovations lead to the following advantages over other systems:  more even engagement of all cutting edgeslonger tool lifeoptimised surfacefewer chatter marksminimised vibrationshigher cutting dataFAHRION is the only manufacturer with a system concentricity of ≤ 3µm for ER Collet Chucks |
Holding torque：
| surface of the collet polished
|
Result: Clamping forces are distributed evenly over the entire cylindrical surface area of the tool shaft
radial forces are optimally absorbed
perfect surfaces are achieved when milling
Damping：
| slots in the collet have a damping effect
Result:
|
