The Milwaukee Electric Tool Corp MT556 is a 6-inch diagonal cutting plier designed for cutting wire, cable, and light fasteners in electrical, mechanical, and general trade work. The comfort grip handle reduces hand fatigue during extended use, making it practical for electricians, HVAC technicians, and plumbers who spend hours working in tight spaces or overhead. Built in the USA, the MT556 is a hand tool intended for professional daily use rather than occasional service calls. Its compact 6-inch length gives adequate leverage while staying maneuverable in confined installations.
The MT556 suits residential and light commercial applications where a reliable cutting plier is part of standard tool kit. Electricians reach for diagonal cutters when trimming wire leads, clipping zip ties, or cutting small-gauge conductors. HVAC and plumbing technicians use them for cutting stranded wire on low-voltage controls, snipping lock wire, and similar tasks. The 6-inch size is the most common format carried by journeymen and service techs across trades.
Designed as a general-purpose diagonal cutting plier suitable for electrical, HVAC, plumbing, and mechanical trade applications requiring a 6-inch cutter.
Always de-energize circuits and verify with a voltage tester before cutting any conductors. Diagonal cutters are intended for copper and aluminum wire and light fasteners only — do not use on hardened steel, piano wire, or live conductors above the tool rating. Inspect jaws and pivot for wear before each use and replace if the cutting edges are nicked or misaligned.
