Dies
A die cuts an external (male) thread onto round bar. Like a tap, it cuts with every edge at once and the torque is high — so the die's material and surface treatment decide whether the thread comes out clean or torn.
THE MATERIAL YOU ARE CUTTING3


Start here. Pick the material you are cutting and the collection filters down to only the tools that work it. The letters P/M/K/N/S/H are the ISO 513 standard, used by every manufacturer — the same letter means the same material in any catalogue.
In detail, per group: [P] Steel · [M] Stainless · [H] Hardened.

Plain and alloy steels — the largest and most forgiving group. They give a long, continuous chip, so chip control is what matters.

Stainless steels. They work-harden locally as you cut them, weld to the edge, and do not carry heat away. They want cobalt, a steady feed with no dwelling, and plenty of coolant.

Hardened materials, typically above 45 HRC. They demand carbide and a thermally stable coating — plain HSS simply dulls immediately.
