Carol Machine Tool Wire: 18 AWG Wire Size, White, 500 ft Lg, PVC, 0.11 in Nominal Outside Dia.

Machine tool wire, commonly called MTW, is a type of hookup wire with a highly stranded bare copper conductor. It is commonly used in the internal wiring of HVAC equipment, machine tools, circuits, and control panels to supply power. It has a durable jacket that is heat-, oil-, and moisture-resistant and is very flexible, making it a good choice for installing in tight or awkward spaces.

Lead, hookup, and machine tool wire are thin, small- to medium-gauge (24 to 8 AWG) insulated wire used to establish internal electrical connections and provide power in appliances, motors, power tools, or other electronic equipment. They are commonly used in product assembly applications in manufacturing facilities.
