Overview
The Jonard Tools CST-4000 is a professional-grade round cable stripper specifically engineered for large-diameter cables ranging from 3/4" to 1-5/8" (19 mm to 40 mm). This tool is designed to provide clean, precise jacket removal for PVC, rubber, PE, and other common distribution cable jackets.
The tool utilizes a versatile spring-loaded, rotating blade mechanism that supports longitudinal, spiral, and circular cutting modes. By providing a controlled and adjustable cutting depth, it effectively strips thick insulation and armored jacket runs while minimizing the risk of damage to internal conductors. This tool is ideal for network infrastructure, distribution, and heavy-duty electrical applications.
