Material and construction - Material: Hard Alloy Steel + Tool Steel. The blade body is made of anodized aluminium steel structure, stable and durable. Adjustable and multi-functional - Blade rotates 90 degrees by activating the blade lever, allowing easy mid-span preparation (ringing and slitting). Wide application - A professional armored cable sheath cutting tool, suitable for feeder cable, center bundle tube cable, layer stranded cable and other armored cables. The main purpose is to cut the armor sheath of the outer layer of the cable to obtain the fiber lead inside. Professional and precision - Adjustable from 0.315 in (8 mm) to 1.102 in (28 mm) for smaller cable O.D. - Adjustable blade depth to 5.5 mm maximum to accommodate different cable jackets. - Designed with accuracy-adjustable blades to avoid damage to the fiber. Use scenarios - Scenario 1: In field fiber deployment, use to cut the armor sheath on feeder cables to expose the fiber lead with minimal risk of fiber damage. - Scenario 2: In data center or telecom maintenance, perform mid-span preparation for ringing and slitting on armored cables during installation or repair. - Scenario 3: Working with center bundle tube cables or layer stranded cables in industrial settings, reliably remove the outer armor sheath to access the fiber leads.
