Features Durable Construction: Made of hard alloy steel and tool steel materials, with an anodized aluminum steel structure, ensuring stability during cable stripping and providing long-lasting performance. Adjustable Blade and Labor-saving Design: The adjustable blade can be rotated 90 degrees, equipped with pulleys, allowing for longitudinal stripping along the wire direction, making the operation labor-saving and stable. Precision and Versatility: Features an accuracy adjustable blade to avoid damage to the optical fiber, with adjustable peeling outer diameter from 4-10mm and cutting depth of 5.5mm, suitable for various cable thicknesses and types. Suitable for Multiple Cable Types: Designed for many core sheathed or armored cables, this tool is ideal for cutting the outer sheath to obtain the internal optical cable, used for installing wires into network and telecommunications equipment. Ergonomic Design: Equipped with a comfortable grip and ergonomic handle, providing ease of operation for the user. Specification: Item Type: Cable Slit Tool Specification: Approx. 4 ~ 10mm / 0.2 ~ 0.4in Material: Hard alloy steel + tool steel, anodized aluminum steel structure Number of Cutter Heads: Single head Product Size: Approx. 131 x 40 x 26mm / 5.2 x 1.6 x 1in Cutting Depth: ≤ Approx. 5.5mm / 0.2in Diameter Ranges of the Model Cables Corresponding to the Colors of the Guide Wheels: Gold: Approx. 8 ~ 28.6mm / 0.3 ~ 1.1in Red: Approx. 4 ~ 10mm / 0.2 ~ 0.4in A. Determine the cable structure. 1. The many core optical cable structure may have a solid inner adjacent sheath and an outer adjacent armor sheath. In order to avoid tool damage, please determine the structure of the cable first. B. Set the cutter head. 1. The slitting blade of the utility knife is equipped with a retractable function. When the sample cable is placed in the utility knife, the depth of the blade can be set. There is a groove at the bottom of the thumb knob A, and the blade can be adjusted by turning the upper screw the height of. There are 10 divisions at the bottom of the thumb knob. The height of the cutter head adjusted by one turn is 1mm. In turn, each scale is equal to 0.1mm. When the distance between the cutter heads is adjusted, the utility knife will have a "lock" on the cable. The sound of "live" can avoid the damage of the internal structure of the cable caused by setting the cutter head too deep. C. Tool Knife Operation: According to steps 1-6, it can be used for internal and external structures with relatively high strength. (longitudinal cutting) 1. Loosen the black thumb nut "A" and rotate the blade to move it longitudinally. (as shown in the figure, the blade cuts radially) 2. Put the cable into the loose tool and adjust the yellow finger knob "B" to an appropriate position. 3. Tighten the black thumb nut until the blade can cut the cable longitudinally. 4.
