An adjustable wire stripper and cutter is an essential handheld tool for electricians, do-it-yourself (DIY) hobbyists, and electronics enthusiasts. The instrument depicted in is a conventional scissor type designed to efficiently remove the insulation material from insulated wire without damaging the metal conductors. In addition, it serves well as a wire cutter.
Design and Functional Elements
The device consists of two black-finish carbon steel jaw assemblies joined at a center pivot point. A single handle contains a manual adjusting screw placed within a slide track. The manual adjusting screw enables users to preset the closure distance of the stripping jaws. Adjusting this setting to fit a particular wire size ensures that the sharp, curved cutters on each jaw assembly only penetrate the plastic outer insulation covering of the wire. The other jaw assembly includes a "SET TO WIRE SIZE" scale having incremental marks. This feature assists users in they establishing the proper calibration for repetitive work.
Ergonomic Considerations and Portability
Both handle assemblies have bright, high-contrast yellow colored polyvinyl chloride (PVC) grip coatings. The molded-in contours provide both a secure, non-slip grasp and reduce the potential for user fatigue when operating the tool over extended periods of time on wiring-related tasks. The RT-126F designation clearly identifies this compact tool as being extremely portable; thus, it can easily be carried in any standard-sized tool belt, pocket, or electronic repair kit.
Proper Techniques for Using the Tool Effectively:
Calibration: Test the adjustment screw on a piece of scrap wire identical to what you plan to use prior to beginning your actual project. As such, you will know whether you obtain a complete removal of insulation.
Avoid Over Tightening: If you set the jaw opening too small and you may nick or cut through the inner wire strand(s). Doing so would compromise the integrity of the electrical circuit.
Cleaning: Remove loose insulation fragments from the jaws periodically using a soft cloth. Apply one or two drops of machine oil to the pivot pins to a maintain smooth action.
