Stanley 89-858 Fatmax Diagonal Cutting Plier

Product Description

The STANLEY 89-858 is a diagonal cutting plier from the FatMax line, designed for cutting wire, cable, and soft fasteners in electrical, HVAC, and general trade applications. The oval head profile provides clearance in tight work areas, and the 13/16 inch jaw length gives the tool a compact cutting geometry suited for precision cuts on small-gauge conductors and zip ties. At 0.41 pounds, the tool is lightweight enough for extended use without fatigue. This plier is non-insulated and intended for use by electricians, HVAC technicians, plumbers, and other trade professionals who need a reliable hand cutting tool on the job.

The 89-858 fits a wide range of trade applications including residential and light commercial electrical work, HVAC control wiring, panel work, and general mechanical tasks. The standard cutter style handles common cutting tasks across job sites and service vehicles. The tool is sold as a single unit and is well-suited for toolbox carry or service van inventory.

Installation Notes

This tool is non-insulated and must only be used on de-energized conductors and components. Electricians and HVAC technicians should follow NFPA 70E safe work practices and verify circuits are de-energized before cutting any wiring. Inspect the tool before each use for damaged cutting edges or cracked handles. Do not use this plier on hardened wire or fasteners beyond its rated capacity, as this may damage the cutting edge.
