Any particular type of end mill recommended? Brand? Carbide vs. HSS? I used HSS last year, but never needed to have an LOC longer than 1/2". Is carbide the preferred alternative for rigidity in this case?

Also, maybe slightly off topic, but any recommendations on reference books/resources for workholding? That seems, to me, to be the biggest hurdle to get over. My team acquired a used CNC mill last year and while it took some time to learn how to operate it, fixturing was the hardest part.
