The Harbor Freight Icon 41-pc Metric Tap and Die Set, No. 59159, features an ultra-tough tungsten molybdenum construction and vacuum-hardened heat treatment that keeps its edges sharp. The taps and dies, which come in coarse, fine, and BSPT, can cut new threads or salvage damaged ones in steel, brass, and aluminum. Tapered starts make alignment and straight cutting easy, while thread gauges enable technicians to make quick thread pitch identifications. The set includes a lifetime warranty.
