You dont owe me an explanation. If you want to make something out of titanium, than that is what you want to use. I made a tool for a few people at work that cannot be purchased in stores. All were aluminum except one guy requested brass. Well brass worked great and looked great. Now there is no way I was going to let his be cooler than mine so I made one for myself in of course, titanium. Did it NEED to be titanium? No. Sometimes it's not about the bare minimum needed for production. For people like me, this is a hobby and there are reasons not considered by "production" guys like COOL FACTOR. The tool i made is the only one there is, the only one there ever will be, and i have already turned down enough money for it to cover the cost of all the expensive tools plus.
I'm not a machinest so all i can offer is this.
Solid carbide endmills and drill bits at low speed and take a good bite. Dont be afraid to feed some material to the cutter. When i tapped a hole i used a new HSS 2 flute tap and alot of tap magic. Cutting was easier than i thought it would be.
