I want to use a bit with a 3/16" shank. I only saw 1/4" collets in the woodshop and was trying to decide if I was going to buy a 1/4" to 3/16" adapter and then I thought it might be possible that the 1/4" collets we have might be designed to accept multiple shank sizes.
To save me a trip of driving all the way back over there, does anyone know if the 1/4" collets that we have also accept a 3/16" shank?
