After decades I resorted last year to a 3 way 3" from Amadeal just to do a specific job, never used since. Must say for the money they are pretty good but wouldn't want to do anything heavy.
Vices will come plain, swivel, tilt, tilt with swivel in an ever increasing height.
You can clamp up in normal vice work pieces at an angle or why not use normal vice and tilt the mill head. Don't buy the drill press tilt vice that's all theyre good for.
Chamfer edges just make sure jobs proud of jaws and drag a cutter down the sides, easy. Apart from specialist cutters I still use a pipe 45 degree debur cutter cut opposite hand so spun opposite direction works very well 20 odd years and used daily. Anything goes.
