The operation would use a process called ablation, or "kinetic separation," where the ore is concentrated as it's mined, so far less ore has to be processed in the mill, according to Glasier.

Cobalt Steel Ball End Mills with Two Milling Ends. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. When one end wears out, turn the tool around for a sharp edge.

Speed: As a rule, tapping is slightly faster than thread milling. Depending on the workpiece material, thread depth, and machine tool speed, the 1/4"-20 thread discussed so far might take 4-5 seconds to tap, and perhaps twice that to mill with a full-profile cutter. Yes, single-plane thread mills with their need to make multiple passes are far ...
