The STANLEY 89-859 is a 7.5-inch diagonal cutting plier built for trade professionals who need a reliable, heavy-duty cutting tool on the job. Part of the MaxSteel line, this plier is designed for cutting wire, cable, and similar materials in electrical, HVAC, plumbing, and general mechanical applications. The cutting jaws are positioned at an angle to the handle, allowing clean flush or near-flush cuts in tight spaces. At 0.56 pounds, it is lightweight enough for extended use without hand fatigue. Licensed electricians, HVAC technicians, and plumbers commonly reach for diagonal cutters during rough-in, trim-out, and service work.
This plier is suited for residential and light commercial service work where a mid-size cutting tool is needed. Common applications include cutting copper wire, zip ties, cotter pins, and small-gauge cable. The 7.5-inch overall length provides enough leverage for clean cuts without the bulk of a larger tool. It fits standard tool pouches and belts, making it a practical everyday carry for field technicians across multiple trades.
Designed as a general-purpose diagonal cutting plier suited for electrical, HVAC, plumbing, and mechanical trade applications requiring a 7.5-inch cutting tool.
Always de-energize circuits before cutting electrical wire and verify the absence of voltage with a meter. Follow applicable NEC requirements when working on electrical systems. Inspect the cutting edges before use and do not use the plier on materials exceeding its rated cutting capacity, as this can damage the jaws or cause slipping.
