I bought a bunch of endmills from a machine shop going out of

The seller told me some of them were carbide.
I saw some of them that were dull grey instead of shiny steel but they
were all magnetic.
Is tungsten carbide magnetic?

Magnetic, but more weakly than steel would be. The density is the
real giveaway - they will be far heavier than a steel cutter of the
same size. Enough so that you shouldn't have to find a steel one to
compare - it will be much heavier than experience tells you it should
be.
