Looking around on eBay for 5C collet kits, I stumbled over a 5C to ER40 tool and a big box of ER40 collets. That adaptor claims to be bored internally for stoppers, so I'd have to assume its bored thru. So if you need less that its passthru, I'm guessing an inch or a few thou more, that kit would be a better choice than a big box of 5C's because the ER40 can give you a 5x tighter grip over a greater length of workpiece than a 5C can. Lightened my card, with ship, $138. 15 ER40 collets included, and a spanner wrench for the adaptor nut. Pretty easy to like. Ought to be here Friday. There are ER40 adaptors for lots of smaller spindles but the 5C would probably be only one of two bored thru, as I'd expect the R8-ER40 adaptor is too. Anything smaller, probably not.
