What Dan_S said. Here's a picture of a 1" R8 collet:
You probably wouldn't want to put your finger in there and tighten the collet/drawbar, but the clamping force on the end mill shank is really light as compared to an end mill holder (picture below). You could probably get away with the 1" collet if you pecked away but I'd be really careful. Otherwise you'll end up posting a catastrophe on the Safety Issues & Equipment forum.
