Can anyone here translate from Japanese?

I was poking around HLJ looking at tools and came across the "Brain Factory" tool listings and then from there went to their site.

Is it a pyroguave-woodburning set type arrangement?

At first I thought they were punches, like a punch an die set, but their site seems to place the tips into an electrically powered hand unit, and some of the photos looks like the tips are used to melt plastic.

Anyone know what's up with them?
