Standards of ER Collets
These collets are usually found in a standard series as: ER-8, ER-11, ER-16, ER-20, ER-25, ER-32, ER-40, and ER-50. The numbers represent the opening diameter of the tapered receptacle in millimeters.
What is the taper angle of a collet holder?
This collet as a taper angle of 6°, the ideal angle for run-out accuracy, gripping force and rigidity. The increased number of slits ensures the uniform tightening and high accuracy of the collet. The collet holder (CTH type) is pre-balanced by previously designing the holder to be as axisymmetrical as possible.
What is the diameter of the collet shank?
Cutters can come in a number of different shank diameters, the common imperial sizes are 1/4 “ and 1/2”, whilst in metric they are 6mm, 8mm, and 12mm. It is important that the shank diameter is correct for your router collet.
