If I'm not mistaken, Diehl used to make Craftsman power tools
for Sears, way back - 1960s and earlier. I don't recognize
them as a handtool maker.

Auger bits come in several different styles. Ideally you want
"double twist" bits - looking at the bit from the end, there
are two flutes, 180 degrees apart. Single twist will work too,
but IMO they're harder to start straight.
The bit should have two "ears" or spurs at the end - single
twist bits sometimes just have one, and "ship augers" don't
have any. For a hand drill you want two for easy cutting.
These get gradually worn down as the bit is sharpened, so you
want to look for bits that aren't too worn.
The center screw should have clean threads, and not too steep
a pitch. This screw pulls the bit into the wood, and needs
to be in good shape for the bit to work. You'll see bits
with steeply pitched screws, those are intended for power
drills (which can cut more aggressively). You will, sadly
find bits where some idiot has ground the lead screw off -
these are useless and can be thrown in the trash.
You'll want bits with a square shank. A brace can chuck a
round shank, but for anything bigger than maybe 1/4" you
can't exert enough force without the chuck slipping.

If you can find them, snag straight and phillips driver bits
with square shanks. A brace is an excellent tool for driving
screws.
Also, keep an eye out for a breast drill. Another good tool
to amaze your power-tool buddies with.
