No Tool and Diemaker uses P series tool steel for any kind of breaking, wiping, drawing, or forming; especially in a stamping press. We use D2 or D4, depending on the stock material. You also don't coin with A-2, not if you're smart. You coin with M-2 or M-4 (not the high speed steel they're talking about), they take compression better than most. No one uses 0-2 for blanking, unless it scissors, I have lapped some good gauges made from it, very stable alloy. Correct about D series but D-4 makes very good high use gage fixtures if you're too cheap for carbide. High speed also has cobalt grade, which is superior to both tungsten or moly for heavy, hot, and repeated engagement.

Great 👍

Awesome! Thanks for sharing!
