Thanks guys, i ordered a solid carbide from McMaster and a diamond wheel from ebay. I will see which one works best for Ti. I have been using the cheap ones from grizzly for stainless and they work fine, but figured i should upgrade for Ti.
onespdfrk, a 4" cutter works fine for what i am using it for and using a cutter that is a little thicker than a hacksaw blade makes the cleanup cut simpler.
