the spark test really doesnt work that good.....plus if you are buying scrap from somebody they might not have a grinder plus your going to ruin the wheel on that persons or shops grinder.

CARBIDE DOES NOT RUST OR PIT

carbide is dense like gold so it is heavier than it looks it is brittle so if you drop it, it will most likely shatter

only carbide or a diamond will scratch carbide, it is the second hardest material on earth next to a diamond and scratching it by hand is very difficult. It will not have a peel when scratched

the number 1 test is with a magnet and the one I use the most, it is LIGHTLY magnetic! at our shop I have a steel drill bit to compare the pull from the magnet.

Heavy and slightly magnetized are the key factors

If you are unsure of it being carbide you can also send me pictures and I can usually tell right away.
