I have the normal calculators out there... but some of these boring heads are

10 inches long .. most of the time I run about .003 to .006 per RPM

looking to cut .180 in one pass 4 inch Dia hole

I'm not sure if you are say your tool is 10" or your cut is 10", or your DOC is .180 or .090. The material you are running and machine you are runnuing it on has a great deal to do with what you are asking to do. With all that said try looking at Everede Tool Co. www.everede.net, I use them for heavy boring.

what type of material? if its aluminum that might work if your setup is rigid enough.Personally on a bore that deep id use two boring heads, one for roughing one for finishing,so it will help eliminate tool deflection.leave like .020 for cleanup or something that way if for some reason your bore is doing something funny at least you could hone it out.

Thats what my plan was ...

just never bored somthing that agressive

well depending on the type of boring heads you are using,it should be relatively simple too do what you want granted its not a really hard material. Any chance you can rough out the bore with long endmills first?,or is that already done? Ive made spindle housings before that were approximately 12 inches long,and used a really long 1.125 endmill too hog em out with and then bored em out,but that was on a HMC. How are you holding these parts?A decent sized surface plate would work well.
