What does ER20 collet mean?
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 are common collet sizes?
The standard series are: ER-8, ER-11, ER-16, ER-20, ER-25, ER-32, ER-40, and ER-50. ER collets collapse to hold parts up to 1mm smaller than the nominal collet internal size in most of the series (up to 2mm smaller in ER-50, and 0.5mm in smaller sizes) and are available in 1mm or 0.5mm steps.
What is the maximum diameter of ER20?
Our ER20 collets have a capacity ranging from . 0625 - . 5000 inches or in metric sizes from 2mm up to 13mm. The number shown on the collet is the largest size that particular collet can hold, but it can be tightened to a smaller size.
