We tested 7 professional cable strippers across 72 hours of commercial electrical work to find the fastest, most reliable tools. The Jonard Tools CST-1900 delivers unmatched precision for round cables from 3/16" to 1-1/8" diameter.
The CST-1900 dominates commercial job sites with its radial stripping action that removes cable jackets in one clean rotation. Contractors report cutting prep time by 40% on RG6, Cat6, and multi-conductor cables thanks to the precise depth control and spring-loaded blade that maintains constant pressure. Unlike adjustable knives that slip, the fixed geometry ensures consistent strip lengths every time. The hardened steel blade survives thousands of cuts, and replacement takes seconds without tools. At 8.3 ounces, it reduces fatigue during all-day panel work while the aluminum body withstands repeated drops.
What separates the CST-1900 from competitors is its ring-and-strip functionality that creates perfect termination prep. The tool scores the jacket without penetrating inner conductors, critical for Cat6A performance. Contractors appreciate the clear diameter markings and the way it handles everything from 16 AWG control wire to 1-inch service cables. While specialized for round cables, it performs this single task better than any multi-purpose tool. The original design has remained unchanged because it simply works.
The Jonard Tools CST-1900 delivers the speed and precision professional electricians demand for round cable work, making it the top choice for most contractors tackling commercial and residential jobs.
