Brought home a few punch blanks, or raw materials, which are little
round things the size of various rifle cartridges. They are made from
some wonder steel, as I discovered when I tried putting one in a
press, against a mild steel washer. The washer was fully defeated by
the punch blank.

According to the factory manager, this is A2 or D2 steel.

I used one piece as a male brake die, but don't know what useful
things one could do with these little ones. An awl comes to mind
first.

I would hate to get rid of them and need one later. So... Any ideas?

They are supposedly hard to machine.

I tried sharpening one pin to the shape of a chisel, and pushed it
through a piece of mild steel with a press. The result amazed me.

It cuts through steel like knife through butter.

They are essentially round HSS tool bits. Grind a flat on one and it
will make a nice insert for a boring bar. You can silver solder one to
a shank and make a special tool. Any that are ground to a "normal
diameter" .250, .375, .500, etc. make nice aligning pins or gages for
setting tooling.

A lot of uses. If I were in your vicinity I'd stop by and pick them up
just to get them out of your garage so you'd have more space in there
:-)

Hey, it's tool steel. Make more tools from them. Punches (duh!),
chisels, alignment pins, dowels, coat racks <giggle>, etc.

As a curmudgeon, I grok that in its entirety.

I will make an awl out of one of them. Also will try to make a chisel
style bit to cut steel bars with my press.
