I ordered a set of ER16 collets from eBay in order to make a precision drill grinding/sharpening jig. At the same time, I ordered two chucks with 100mm spindles, one for the sharpening jig, the second for a toolpost drill setup at some point in the future.
The collets are still in transit, but the chucks arrived today. One is marked ER16, the other ER16A. The nuts are different sizes, and the thread on the ER16 is finer. I don't have any ER16 collets to check if there's any difference in fit.
Before I go and have a whinge at the seller, can anyone here confirm if there's any material difference between the two types?
