Since a bridgeport isn't very stiff in general and the bearings are not heavy-duty, I try to limit the tool projection as much as possible, unless there's some sort of interference; I don't know of a better method to limit tool overhang, and get the best runout in addition, than using a good quality r8 collet. I have a nice set of ETM ER40 ...

11-07-2010, 04:17 PM. I personally prefer the ER32 for most Bridgeport and smaller mills. Here's why: - Less overhang. - Less Z clearance lost. - A bit easier to fit in tight spaces. - 3/4" is about the largest tool shank you'll want to drive anyhow, given the limited power and rigidity of R8 and typical mills.

And a pissant R8 weighs ounces. ER-40 holds big tools, it's forgiving on diameters, it has friggin' gobs of grip. I use them all the time on a 20 hp horizontal mill at work. No reason to use them on a 5 hp bridgeport or similar. ER-40 is way too damn big to put on a R8 shank, but obviously someone would do it. The overhang is just unacceptable.

Re: Truing a ER40-R8 adapter. I disagree with some of what has been said. First, I will say that no modifications to the R8 taper on the spindle or tool holder should be done UNLESS there is is a problem that can be verified. The spindle taper can be checked for runout at various distances from the nose with an indicator.

I have an ETM ER-40 chuck like that and an ER-32 chuck that fits Tormach's TTS system. Both work well. The ER-32 slips out of the TTS 3/4" R8 holder easier for bit changes. The ETM one requires a spindle wrench up top to hold the spindle still while I loosen and tighten the ER chuck nut down below. Its a bit more cumbersome but the …

I decided to try this one out as it is mid priced and has a reasonable TIR spec. The claim is 0.0001" at the collet face. I figured if I wasn't happy I would send it back and spring for a Bison or similar. Prior to installing, I thoroughly cleaned the taper in the Bridgeport and tested it with...
If you change tools a lot, R8 is a darn convenient system. I have had R8 on my mill-drill for over 20 years, ETM ER40 on a versa-mill portable mill for "quite a few years", and recently added an ETM ER40 to a South Bend milling machine with 30Taper. I like the more rigid 30taper over R8 functionally.

So I'm wonder if there is some reason to get ER40 vs ER32 and a seperate 1" end mill holder. Do the ER40's hold better on say 1/2" shanks? FWIW, I plan to use the 1" mill just to get a .500 inside radius, it will be light duty milling only. Also I have a basic set of 12 R8 collets as well.

1. Nov 15, 2009. #2. I can't imagine it being more accurate than 5C. After all, if it was good enough for Hardinge, it's probably good enough for most anything. ER's are nice for other reasons, mostly having to do with needing fewer collets hanging around. If you get a nice set of 5C's, I'd be surprised if you preferred the ER's, but to each ...
