1. On a hunch, or perhaps it was something someone said earlier, I checked
those stellite bits and found that they are not magnetic. So back to the
bit bin and pulled out all the non-magnetic bits. It included:

a. All the stellite bits and blanks.
b. Some called "Tantung G."
c. Some called 525.

Are these latter two also Stellite? If it's not magnetic, is it
Stellite?

2. I noticed that some of my non-magnetic bits had an etched notice
"cutting surface." I've never seen that before. The tool blank doesn't
seem to be a composite. What is this?

3. I noticed that all the ground stellite bits had the cutting surface
opposite the etched "stellite" label. Is there a preferred cutting surface
for stellite? Or was it just to be able to keep track of what kind of bit
is what.
