| description | A method of removing material in a threading operation from a workpiece comprising a ferrous alloy having a hardness between about 50 Rockwell C and about 65 Rockwell C using an uncoated cutting tool, the process comprising: providing an uncoated cutting tool having body containing a pocket where a superhard blank is brazed using a braze alloy into the pocket to form a braze joint wherein the braze alloy having a liquidus temperature of at least about 900 degrees Centigrade wherein the braze alloy is selected from the group comprising a nickel-gold braze alloy containing nickel and gold, a copper-gold braze alloy containing copper and gold, a gold-copper-nickel braze alloy contains gold and copper and nickel, a silver-titanium-copper braze alloy containing silver and titanium and copper, and a silver-palladium braze alloy containing silver and palladium; and engaging the workpiece with the uncoated cutting tool on multiple passes wherein each pass removes a volume of material substantially equal to or less than the volume of material removed from the workpiece in the previous pass. |
