Just got my new milling machine up and running and the first project was milling out the rear sight pins that hold the mount on my Mosin Nagant. Worked really well after melting the solder.
Anyway, getting back to the subject line, I have a few AR15 80% lowers some in polymer and some aluminum and was wondering what
types of end mills I should get to do the job correctly. I suspect maybe different ones for both materials. As a matter of fact I do not really know what speeds to use either. My experience with mills are about 15 years but just using what was set up to do little jobs at work so any input would be appreciated.
