These pliers sets include multiple pairs of wire-twisting pliers in various sizes. Wire-twisting pliers lock their jaws onto the loose ends of wire and spin the wire to twist it together. Also known as wire twister pliers, they make tight, consistent twists that resist unraveling. They are commonly used to form decorative twists for jewelry and safety wire twists that lock down fasteners in aircraft and high-vibration machinery.

Welding pliers provide a multifunction tool to prepare MIG guns for welding and clean them up after use. They have a wire cutter to trim stick-outs to length, gripping zones to loosen nozzles and contact tips, a square nose to grip and draw wire, reaming edges to remove spatter, and hammer faces to remove slag.

Hole-punching pliers strike their punch against their anvil and drive holes through leather, rubber, textiles, cardboard, and soft plastics. Also known as revolving punch pliers, their rotary head holds interchangeable punches in a range of diameters to make different-sized holes. Each punch rotates into place to align with the anvil and cut cleanly through material. 

Nail pulling pliers clench their jaws onto fasteners and roll on their rounded head to pry them out. They provide a firm grip and more leverage than nippers to remove stubborn or damaged nails and staples. 

Cannon plug pliers have curved, padded jaws to grip and turn electrical connectors, quick-disconnect couplings, pipe, nozzles, and other rounded parts. Their soft jaws prevent scratching and marring of plastics and soft metals.
