Carrier cut good w carbide emill

[panaceabeachbum]

I was getting ready to cut the bolt carrier on edm and thought it would be nice to have a little ledge to set cocking tab on . $6 1/4" emill from enco worked great. Material still hard to cut so slow going probably 10 min to mill, broke one tool

I love carbide! I use it a lot it gives a better finish on my stuff.
Recently got a few of those end mills that take the Carbide inserts.I'm cutting 4140 hardened plate like butter!
