Default Face mill arbor

Looking for a shell mill holder.

Straight shank. 3/4 diamiter to fit in a 3/4 collet. 1" diamiter to fit the shell/face mill. Any ideas where to look?

What number taper does your mill have?
You would be better off getting the correct holder for it instead of relying on a collet to hold it.

As Dan says, if you want to make that face mill usable it’s much better to use the proper tapered shank to fit your mill.

What size of face/shell mill is it?

Always seems to me that almost anything with inserts over an inch or so in diameter avoids straight shanks.

Holding a face mill in a collet is a very bad idea,
you will not be saving any money either.

I would buy the correct arbor for your mill.

I assume it is a Bridgeport or Bridgeport clone? R8 spindle?

Gorton Mill with a Nmtb 40 spindle. Has a Kwick Change 200 holder in the spindle.

I've found this...
http://www.tools-n-gizmos.com/store/...xm=on&ppinc=1a

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.

Seen this from Shars
https://www.shars.com/3-4x1-face-shell-mill-tool-holder

I know it sounds silly but I'm actually pretty nervous to break loose the drawer in the spindle and take the Kwick Switch holder out.

But then I could use something like this

https://www.shars.com/1-nmtb-40-face...ll-tool-holder

I'm not looking to do any precision machining right now. I'm just wanting to try different tools and things.

Are you talking about a shell mill or a face mill? Makes a difference. What type of machining are you looking to do? Compared to a face mill or an end mill a shell mill can exert a lot of force on a tool holder. In a vertical milling application it's much more common to run face mills or endmills. Shell mills are more commonly run on outboard suported arbours on a horizontal milling machine...

I consider face mills to be cutters with inserts that mount to a arbor.

Shell mills are like plain milling cutters on a horizontal mill but will fit on a face mill arbor.

Right now facing off some square tubing to slide into each other. 1 1/2 inch wide.

Use a long end mill for that, the larger you can fit in the mill the better. A 3/4 or 1” end mill long series will work well.

I’ve also used roughing cutters (like a serrated edge) for stuff like that.
