This tool set includes Klein's Large Cable Stripper (Cat. No. 21051) and a High-Leverage Cable Cutter (Cat. No. 63225SEN). Klein's Large Cable Stripper safely removes the insulation on MTW, THHN and THWN-2 cable without nicking the wire. Simply insert the cable and twist for precise, clean cuts. The clover design features four different sizes from 250 MCM - 2/0 in one tool. Put down the utility knife for a safer, easier and more precise cutting tool. This high-leverage cable cutter cuts aluminum, copper and communications cable. Cable-gripping shear-type jaws and a high-leverage design translate to 30% less force needed to cut as compared to Klein's 63050 model. Through-hardened, not case-hardened, cutting surfaces increase the durability and life of this tool.
