I found out recently who invented the ER collet and I thought that makes sense. I'll give you a hint they are a pretty big name now but I'll bet most of you don't buy or use this brand in your shop unless you are in a high tolerance / big $$$ shop. When they invented it it was originally called an E collet.
What's your guess?
