Key Applications and Projects

• Automotive Audio & Lighting: Quickly stripping and prepping wiring harnesses for car stereos, LED light bars, and alarm systems without damaging the stranded wire.

• 3D Printer / CNC Wiring: Stripping multiple conductors on a stepper motor ribbon cable simultaneously to attach JST connectors.

• Household Electrical Work: Speeding up the installation of light switches, ceiling fans, and wall outlets.

Unlock New Capabilities (Project Evolution)

• The Master Wiring Harness: Building a custom control box for your CNC machine requires terminating hundreds of wire ends. Manual strippers will leave your hands cramped and blistered. Evolve your workflow! By using the YTH-78-318, you can grab a handful of stepper motor wires, dial in the tension knob for perfect silicone stripping, and bare all the wires in seconds. Pair this tool with a ratcheting ferrule crimper, and you can build a professional, industrial-grade electronics cabinet in a fraction of the time!

Package Includes:

• 1 x YTH-78-318 Self-Adjusting Wire Stripper and Cutter

FREQUENTLY ASKED QUESTIONS (FAQ)

1. How does a "self-adjusting" stripper work? Instead of having specific-sized holes for different wire gauges, the jaws clamp down flat on the wire. The mechanism automatically gauges the thickness of the insulation and pulls it apart, leaving the internal copper untouched.

2. What is the metal knob on the top for? That is the tension adjustment knob. It controls how hard the blades bite into the wire.

3. When should I tighten the tension knob? If you squeeze the handle and the tool just slides off the insulation without stripping it, tighten the knob so the blades bite deeper.

4. When should I loosen the tension knob? If you notice that the tool is ripping off copper strands along with the plastic insulation, loosen the knob so it grips less aggressively.

5. Can it strip flat ribbon cables? Yes! Because the jaws are flat and wide, you can insert a flat multi-core ribbon cable (like those used on 3D printers) and strip all the wires simultaneously.

6. Does this tool also cut wire? Yes. It is a 2-in-1 tool. There is a built-in wire cutter located below the main stripping jaws.

7. Is this tool safe for solid core household wire (Romex)? Yes, it can strip solid core copper wire (like 12 AWG or 14 AWG) easily.

8. Is this safe for fine stranded wire? Yes, because you can dial in the tension, it is excellent for stripping fine stranded wire without losing any delicate copper threads.

9. What is the length of the tool? The tool measures exactly 185mm from top to bottom.

10. How wide do the handles open? In their resting state, the handles span 75mm across the bottom.

11. How far do the handles compress when squeezed? When fully squeezed, the handles close down to a span of 35mm.

12. Can it strip the outer jacket of a multi-core cable (like a USB or power cable)? Yes, it can strip the thick outer jacket off a multi-core cable, exposing the individual insulated wires inside. You can then use the tool to strip those smaller wires.

13. Is there a length guide to control how much wire is stripped? Yes, the red jaw assembly features a small molded-in plastic ruler/stop guide, allowing you to strip consistent lengths (e.g., exactly 1/2 inch) every time.

14. Does this tool crimp terminals? No, the YTH-78-318 is strictly a 2-in-1 stripper and cutter. You will need a separate crimping tool to attach terminals.

15. Are the handles comfortable? Yes, the plastic handles form an ergonomic pistol grip that uses the strength of your entire hand, which is much more comfortable than traditional plier-style strippers.

16. Will this cut steel wire or thick bolts? No. The built-in cutter is strictly for soft copper or aluminum electrical wire. Trying to cut steel wire, coat hangers, or bolts will permanently dent and ruin the cutting blade.

17. Can I sharpen the cutting blade? No, the blade is integrated into the complex mechanical linkage. If it becomes dull over years of use, the tool should be replaced.

18. Why is it called the "78-318"? That is the manufacturer's specific model number for this style of ergonomic self-adjusting stripper.

19. Does the tool spring back open automatically? Yes, there is a heavy-duty internal leaf spring visible between the handles that resets the tool to the open position after every squeeze.

20. Can I use this on live electrical wires? Absolutely NOT. The plastic handles are not rated for high-voltage electrical insulation. You must always disconnect the power from a circuit at the breaker box before stripping or cutting wires.
