I purchased one of indexable end mills from Enco, I need to do some facing on a piece of 4140 for a project. I have never used one like this as I have always used standard end mills or a fly cutter so........... I got to thinking (a dangerous habit I have) it might come in handy. I ordered the correct inserts for alloy steel but having never used one I hoped to solicit some tips on its use. It is the 1 1/4 diameter http://www.use-enco.com/CGI/INSRIT?PMAKA=422-3012
Any help would be apprecated.
