I asked this question in another thread but did not get an answer. Thought I might try again.
Was making a cut with a .5 inch mill when things went :toilet: I had made some cuts on the lathe without a problem.
This is my first experience with drill rod so I thought my end mill was bad. Put on another and it promptly quit cutting also. Just to verify they were bad, I put in some aluminum and both end mills cut really poorly. More like scraping than cutting.
So I am stuck not wanting to break out another end mill until I have some idea of what happened. I suspect localized work hardening ( even though I have never actually experienced it ) but it could be I just don't know what I am doing. ( much more likely )
Wondering if I need a better end mill? I am open for suggestions before I doom one of my new end mills to a very short life.
