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 multi-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 to set the height. 2. There are 10 divisions at the bottom of the thumb knob. One full turn adjusts the cutter head height by 1mm. Each scale division equals 0.1mm. 3. When the distance between the cutter heads is adjusted, the utility knife will produce a "click" sound, indicating lock engagement. This helps avoid internal cable damage caused by setting the cutter head too deep. C. Tool Knife Operation: 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. Insert the cable into the tool and adjust the yellow finger knob "B" to an appropriate position. 3. Tighten the black thumb nut until the blade begins to cut the cable longitudinally. 4. Pull the tool along the cable to strip the sheath. For harder cable sheaths, slightly rotate the blade to adjust based on cable hardness. 5. Loosen the black finger nut, rotate the tool 180° around the cable, then re-tighten the black knob for a second longitudinal cut. 6. Use diagonal pliers or a screwdriver to separate and trim the cut cable sheath. For Cables with Stronger Sheaths (Optical Cable Cutting): 7. Position the tool at the center of the optical cable sheath for longitudinal cutting and slide it to the desired location. 8. Loosen the black finger nut "A", rotate the blade 90° to set for radial cutting, then re-tighten the black knob to set blade depth. 9. Rotate the tool around the optical cable to complete the cut. 10. Pull back the cut sheath and trim as needed. Features: 1. Made of hard alloy steel and tool steel with anodized aluminum steel structure. Drum-shaped cable follower ensures stability during stripping and smooth operation along the cable direction. 2. Adjustable blade with 90-degree rotation capability. Equipped with pulleys for longitudinal stripping, enabling labor-saving and stable operation. 3. Precision-adjustable blade design helps prevent damage to internal fibers. Adjustable peeling outer diameter from 4–10mm, cutting depth up to 5.5mm. Suitable for various cable thicknesses. Blade is replaceable. 4. Designed for use with multi-core sheathed or armored cables. Intended for cutting the outer sheath to access internal optical cables. Ideal for installing wires into network and telecommunications equipment. 5. Cable slit tool for efficient and controlled cable preparation.
