That is a 2 flute indexable face mill that uses SEHT1204 insert. Its
stiffer than a lot of other options, but it still sees some flex under
heavy cutting loads.

I regrind an old end mill that way for roughing unknown scrap or auction steel, which is most of my stock, by tilting the grinder fixture onto
the relief grind angle. The bevel is around 0.020" high, and lasts
longer than a sharp tip. Also it doesn't create as sharp of a stress concentration on milled wrench flats. After several regrinds it needs to
be sharpened the usual way to widen the central flat. It's one of a
batch of dull name brand end mills bought second-hand.

That's very nice and professional, you are definitely a real machinist.
I was thinking an in-shop mill fixture but of course yours has to go to
the school. What did you paint it with, to stand up to student abuse
(like my lathe)?
I began painting my projects after buying the 2" RA air sander that
cleans up steel well and quickly. I'm using Rustoleum 2X Paint & Primer which stands up to metal banging together reasonably well, after a day
in the sun to cure hard.
After being a high school student for the 3D CAD class I think I
understand the concepts, choosing the best 2D surface to extrude was
easy and I've worked as a paper and CAD 2D designer.
persuaded to buy a Bambu A1 but haven't thought of anything I really
need that can't be made as good or better from machined metal or Teflon/ Delrin. I don't intentionally create monsters.
The class dwindled until I was the last, so the instructor gave me a
fast tour of the advanced professional features like creating a
magnified detail of a small area, the characteristics of various
filaments and deflection vs moments of inertia, and I showed him what
I've found for small affordable load cells and crane scales that could
test student bridge models.
The school welding shop is set up pretty well to practice real-world structures the night instructor has built in his business. Each bench
has rotary chucks for welding tubing. I took the class before the
upgrades and had to jig up the practice tubing cluster on scrap and firebricks after fishmouthing the pieces at home. https://www.aircraftspruce.com/catalog/mepages/4130bargainbag.php

Apparently I was lucky. The two NH towns whose schools I attended had
well known prep schools and a fair number of faculty brats in the public system, one is the school John Irving dissed in "Garp", though it was
good enough for his sister. The result of them plus the children of WW2
vets who became self-made professionals (me) was enough kids who knew
the value of education to drown out the losers and maintain a friendly competition to do well. The friend I competed with for top grades in Drafting was the son of an architect, in wood shop it was the son of a surgeon who was building a sailboat.
The towns hired inspiring teachers to match. When my history teacher was promoted to vice principal his replacement was Christa McAuliffe. The introductory English and History classes in college were below the
levels from high school.
At the first school I ate lunch at the large central table with the
class officers, all supposedly respectable. I made and sold them little folding pocket catapults that could silently launch a pea or bit of
Jello half way across the room, limited by ceiling height. We would sit quietly eating with our arms down while provoking food fights among the troublemakers along the back wall.

Your definition of who the trouble makers were may be faulty.
