$140 when I look at it logged in as my account, set up an account and you should see a discount. List is around 216.

I suggest you buy a Bridgeport with an R8 spindle. You will save a small fortune in holders over NMTB-40. Then sell the Gorton mill.

e-BAY, if money is an issue.

will this work ? 1-1/2" proj may be a bit much.

When it comes to interrupted cuts especially in steel you should look for cutters, face-mill that you can change or sharpen yourself like the cheap ones that came with the table-top milling machines that use run of the mill tool-bits, then there is fly-cutters.

You are not going to get any life for your shell-mill in steel, then what?
Save your shell-mill for aluminum.

I ened up getting a 1" diamiter end mill off Amazon. Way faster then the 5/8 endmill I was using.

Im not sure if my speed indicator is right but I'm running about 220 rpm.

Then the pictures of a shell/face mill I have.

But just can't afford it right now. I do not have a shell mill as of yet either. I think....might have a few boxed away.

I'm not looking to do any precision machining right now. I'm just wanting to try different tools and things.
Tim, Cat40 is a solid and very accurate tool holder system.
The banggood boys are not expensive. I find that I do almost all the end mill stuff now out of my ER32 collets.
If you get a collet set, don't go with the 16, get the ER32 set.
Once you have a few tool holders, people start giving them to you. I was recently given a Jacobs 1/2" chuck and a NMTB40 to JT taper adapter. I may use it someday.
Because the cat40 is so common in industry, a guy puts one in the lunch pail, and then finds his drill press is a different taper so the chuck is not usable.
Edit
Because the CAT40 and NMTB40 are the same taper and same length, they will interchange. You have to remove one drive lug from the spindle, and then the two types will both fit the Gortin. One drive lug is more than enough to drive all the tooling you want.
