I have an ER32 collet chuck with 11 collets. A recent project revealed that I am missing collet sizes to hold some SAE drill sizes.
To figure out what I collets I was missing I made this chart showing the SAE drill size up to 1/2" and their corresponding SAE ER collet size.
Hope this is useful to others.
