Hi another stoopid question, what would be best to get MT or R8 in a milling machine, what's the pros and cons of each?
Thanks for any replies.

Get R8, MT's are often a sod to remove ...

Can you still use MT drills and reamer with R8 is there an adaptor?

Dosent it kind of defeat the point of buying a R8 machine and then using it with an R8 to MT adaptor :scratch:

If you might want to purchase used tooling, the choice may well depend upon what country you live in.
-
If I didn't have the tooling already I'd probably buy R8. All my tooling is MT (2, 3 & 4) and some 30INT.

Not necessarily; nearly all my tooling is R8 (or collet based), but that long drill I used came with an MT end. They don't do 'em in R8... So, 1 adapter later...
IMHO, R8 is a better system for vertical milling, as it's less likely to jam up, and also the tools are less likely to fall out if they don't take a drawbar (I'm thinking drills here).

My little mill is MT3, and I REALLY don't like having to beat the taper apart. However lightly I've pinched the drawbar....... (http://forum.thescubasite.com/sad/sad0122.gif) (http://www.thescubasite.com)
If starting fron scratch, I would go for R8. :thumbup:

Thanks for the replies I didn't know what the pros and cons were but would like to be able to mill, drill and ream on the same machine, I have some MT drills and reamers but never owned a mill before.
If I got the R8 and used an adaptor for the MT drills and reamers would I loose some of the spindle to tabe length?
-
My mill has a .75HP motor and MT3 spindle. I think MT3 gives you a range of up to 3/4" tooling (which is fine for a .75HP motor) and with R8 you can go up to 1" tooling which again, I think may be too much for my machine. As a 'Do over' I'd look for a 1HP x R8 machine.
my 2 pesos, and yes you will lose about 1" in table to spindle clearence with an adaptor.
cheers,

I do most of my drilling in smaller sizes, mostly. After swapping the original 13mm chuck for a 10mm one, I gained extra height/ clearance......

Thanks again for all your replies I'm getting a better undestanding now, I've seen quite a few posts about difficulties removing MT tooling. It's looking like R8 is the way to go.
The hole sizes to drill and ream would be up to 1"
I don't have a big budget for the miller as I'm bearing in mind the tooling which I will need to buy, I'm already looking on ebay to get some sort of costing for the basic tooling.
Thanks again, all replies appreciated.
