32-Piece HSS Tap and Die Set with Wrenches Metric cut M3-M12 Hand threading tool Tungsten carbide tap

Taps and dies are tools used to create threads in all kinds of metalworking projects. A tap is used to cut or form a thread on the inside surface of a hole, effectively creating a nut, while a punch is used to cut or form corresponding bolts. Both tools can also be used with cutting oil to clean dirty, rusty, or worn threads on old nuts and bolts, such as automotive spark plug threads, which often suffer from corrosion and carbon buildup. Made from high-quality alloy steel, these taps and dies, when used accurately with cutting oils, will tap and thread typical metals such as carbon and alloy steel, cast iron, aluminum, brass, and bronze. Three- and four-flute taps and dies with coarse and fine tapered threads. The sharp edges help align and start the tap in an unused hole. Cut new material or drive out slightly damaged threads, such as old screws, spark plugs, nuts, and bolts affected by rust. The wrench handles hold the tap and workpieces securely. The milled ends of the adjustable tap and die handles provide a slip-free grip for tough jobs. The tools are neatly stored in a clearly labeled, organized, and accessible case. Includes taper, intermediate, and plug taps, and a die for each size.
