It is not metric — for metric applications, a separate metric tap and die set would be needed.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What materials can these taps and dies cut threads in?\u003c\/h4\u003e\n\u003cp\u003eA: The alloy steel construction allows these taps and dies to cut threads in a wide range of materials, including mild steel, cast iron, aluminum, brass, copper, and most plastics. For hardened steel or stainless steel, extra care and cutting fluid are recommended for best results.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is a cutting fluid or lubricant required when using the set?\u003c\/h4\u003e\n\u003cp\u003eA: While not included, using a cutting fluid or tapping oil is strongly recommended for best performance and longevity. Lubricant reduces friction, improves thread quality, and extends the life of the taps and dies — especially when working with harder metals.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the set include storage for all 40 pieces?\u003c\/h4\u003e\n\u003cp\u003eA: Yes!
