Assorted Hole Tool Steel Draw Plate U Reduce and shape the thickness of brass, copper, gold, silver, platinum or soft steel wire. Made of thick, high-grade tool steel, carefully stamped with style identifying letter and hole sizes. The holes are progressively smaller, in proper increments, so that wire drawn from a preceding hole will go through the next hole easily. Occasional annealing will keep wire soft, and bees wax can be used as a lubricant. Has 60 holes of assorted shapes; square, round, and half round. Size range of holes is approximately 1-4mm.
