No-niks .021 dk blue strippers Designed for removing insulation from high-quality, coated wires without nicking the conductor. Plastic heads center and support the wire on both sides of the cutting blades. Blades score the insulation completely around the conductor, but do not completely cut through it to expose the conductor. Cutting blade diameters range from 0.008" to 0.054". Cutting apertures are accurate to within .0005". Each tool is made to strip one wire size only. No adjustments are needed. Handles are color-coded and cutting diameter sizes are clearly marked on each tool for easy identification and selection. An arrow on the plastic head indicates the direction pressure should be applied when stripping. No-Nik® strippers are available to handle either standard insulated wire or optical fibers. 5-1/4" O.L.
