[TheForge] tungsten for punches?

[Bruce .]

I vaguely remember a discussion on this forum that touched on the use of
tungsten punches.  Was there any reality to that notion?

In particular, would it make any sense to make a tungsten punch in smaller
sizes?  TIG rods are available 0.040" up to 5/32" -- just the range where
punching is difficult because the punches heat and bend.  My thought is to
encase most of the rod in a close-fitting steel sheath (tube), if necessary
to prevent bending and to give a steel surface for striking.

Is this idea way off-base?  Your thoughts?
