Hi all, I was slowly cutting threads using HSS and had this what i call galling issue. Then I bought a Carbide 60 degree cutter and had similar issues. I went a little deeper and the tip broke off, so scratch one brand new bit. Slow speed. Not sure why this happening but I'm not very experienced.
Somehow it seems like maybe the 1018 steel part metal quality may be an issue?
Stumped!
