I'm notching some 3/4" black iron pipe in my mill with a 1 1/16" M-42 endmill (side cutting). I tried to identify the type of steel using my Machinery's Handbook, but it only lists the dimensions and flow volumes for schedule 40 black iron pipe.
I'm guessing that is it mild steel (HR) and that a good place to start for a spindle speed is 100 fpm.
Any suggestions?
