This M2 steel tool bit from Pacific Sintered Metals won the grand prize in the combined hand tools and recreation category. The bit goes into an installation tool that expands and secures tubes within a heat exchanger. Pacific Sintered makes the parts to a full-density of 8.1 g/cm3, using a compaction and liquid-sintering process. For extra wear resistance, the part is then heat treated to 61-63 HRC and triple tempered for toughness. The part's thin and stepped sections are molded near net-shape, which helped contribute to a 90 percent cost reduction compared to machined-wrought M2 bar stock.
