Features

• Complete with sheath protection
• Blade manufactured of tempered stainless steel
• Curved blade for easy stripping
• Excellent cutting quality – stays sharp

Key Features:

• Insulated Handle: The handle is designed with high-quality insulation to protect against electrical shocks. The insulation is typically rated for a specific voltage, ensuring safety when working near live electrical circuits.
• Sharp, Curved or Hooked Blade: The blade is designed to precisely cut through the cable’s outer coating or insulation without damaging the inner conductors. The blade is often curved or hooked to facilitate controlled, clean cuts around the circumference of the cable.
• Ergonomic Handle: The handle is ergonomically shaped to provide a comfortable grip, reducing hand fatigue during extended use. The non-slip surface ensures a secure grip, even in wet or oily conditions.
• Blade Guard: Many insulated coring knives come with a protective sheath or blade guard to prevent accidental injuries when the tool is not in use.

How to Use an Insulated Coring Knife for Cutting Cable Coating

1. Preparation:

• Inspect the Knife: Check the knife for any damage, particularly to the insulation on the handle and the sharpness of the blade. If the insulation is damaged or the blade is dull, do not use the tool.
• Wear Protective Gear: Always wear insulated gloves, safety goggles, and other appropriate personal protective equipment (PPE) to protect yourself from electrical hazards and accidental cuts.
• Secure the Cable: If possible, secure the cable in a vice or with a clamp to prevent it from moving during the cutting process.
  
  

2. Cutting the Cable Coating:

• Position the Blade: Place the blade of the insulated coring knife at the point where you want to remove the coating. The blade should be angled slightly to ensure a clean cut.
• Make the Initial Incision: Apply firm, controlled pressure to make an initial incision through the cable’s outer coating. Be careful to cut only through the outer layer without nicking the inner conductors.
• Circumferential Cut: For larger cables, rotate the knife around the cable while maintaining even pressure to cut the coating all the way around. For smaller cables, a single, precise cut may be sufficient.
  
  

3. Stripping the Coating:

• Peel Back the Coating: After making the circumferential cut, you can peel back the coating using the knife or your hands, depending on the thickness of the material. For thicker coatings, you might need to make a longitudinal cut along the length of the section you wish to remove.
• Remove the Coating: Gently pull the cut section of the coating away from the cable, exposing the inner conductors. If the coating is stubborn, you can use the knife to assist in the removal.
  
  

4. Post-Operation:

• Inspect the Cable: After removing the coating, inspect the inner conductors to ensure they are not damaged or nicked. If any damage is found, cut the cable back and start again.
• Clean the Knife: Wipe the blade clean after use to remove any residue or debris. This helps maintain the tool’s effectiveness and longevity.
• Store the Knife Safely: Store the knife in a secure location, preferably in a protective sheath, to prevent accidental injury and maintain the insulation integrity.
  
  

Safety Tips:

• Cut Away from Your Body: Always direct the blade away from yourself to avoid injury.
• Keep the Blade Sharp: A sharp blade ensures cleaner cuts and reduces the risk of the blade slipping.
• Check the Insulation Regularly: Regularly inspect the handle’s insulation for wear or damage. If the insulation is compromised, replace the tool immediately.
  
  

Maintenance:

• Routine Inspections: Periodically check the condition of the blade and the insulation on the handle.
• Blade Sharpening/Replacement: Keep the blade sharp or replace it if it becomes dull.
• Proper Storage: Store the knife in a dry place, with a blade guard or sheath, to prevent damage and maintain its insulating properties.

By using an insulated coring knife properly, you can safely and efficiently remove the outer coating of cables without damaging the conductors, ensuring that your work is both safe and precise.
