Hi, tungsten is a tuff metal, very difficult to machine. usually molded to
shape and or ground with diamond. it can withstand great heat, it tends to
get brittle several hours after being melted. threads could be ground into
it with diamond wheels= very expensive for the average person. as for
drilling only with diamond drills $$$$$ cul brian f.
