Product Information

Full details

The Knipex CoBolt S Compact Bolt Cutters (160mm) are designed for professionals and DIYers needing exceptional cutting power in a compact tool. Its key benefit is achieving high cutting performance with less physical effort, making it ideal for tight spaces. A potential caveat is its specialized nature, best suited for cutting hard wires, bolts, and springs rather than general-purpose cutting.

FAQs

What is the maximum diameter of material these cutters can handle?

The Knipex CoBolt S has specific cutting capacities: soft wire up to 5.3mm, medium-hard wire up to 4.8mm, hard wire up to 3.6mm, and piano wire up to 3.3mm.

Can I use these to cut electrical wire or cable?

These cutters are designed for solid, hardened materials like bolts and wires, not for cutting stranded electrical cables or wires.

How does the lever action benefit me?

The efficient lever action mechanism amplifies your force, allowing you to cut through tough materials with significantly less physical effort compared to standard cutters.

Why is the cutting edge induction-hardened?

Induction hardening makes the cutting edge extremely hard (approx. 64 HRC), providing superior durability and the ability to cut through hard materials like bolts and springs effectively.

What does 'slim head' mean for usability?

A slim head means the tool is designed to fit into very tight or confined spaces, making it easier to get the cutters precisely where you need them for cutting.

How do I maintain the cutters for longevity?

Regularly clean the cutting edges, apply oil to the joint for smooth operation, and store them in a dry environment. Avoid cutting materials beyond their specified capacity.

Are these suitable for left-handed users?

The design is symmetrical, and the primary function of cutting is not impacted by handedness. However, the grip and leverage feel may be optimized for right-handed use for some individuals.

Troubleshooting

Cutters are difficult to open or close.

Clean the joint mechanism and apply a small amount of oil. Ensure no debris is lodged in the joint.

Cutting edges are not making a clean cut or are slipping.

Check the cutting capacity chart. Ensure the material is within the specified limits for soft, medium-hard, hard, or piano wire. Clean the lasered cutting edge.

Noticeable rust on the cutters.

Lightly sand the rusted areas with fine-grit sandpaper or steel wool, then wipe clean and apply a protective oil coating. Store in a dry place.

Cutting edge appears nicked or damaged.

This indicates the tool may have been used on material harder than specified. Minor nicks might still allow for cutting, but significant damage may require professional sharpening or replacement.

Pros and Cons

Pros

  • Exceptional cutting power for its compact size.
  • Designed for minimal user effort due to efficient leverage.
  • Excellent accessibility in tight or awkward spaces.
  • Durable construction with induction-hardened cutting edges.
  • Precise and secure cuts due to lasered edges and gripping surface.

Cons

  • May be overkill for soft or thin wires where less power is needed.
  • The specialized cutting edge might wear faster if used on materials outside its intended range.
  • Not designed for cutting cables or flexible wire bundles.
  • 160mm length limits reach for very large or distant objects.

Setup, Compatibility & Care

Setup: These bolt cutters are ready for use straight out of the box. No assembly or setup is required.

Compatibility:

  • Materials: Best suited for cutting medium-hard wire (up to 4.8mm), hard wire (up to 3.6mm), and piano wire (up to 3.3mm). Can cut bolts, nails, screws, and springs within these diameter ranges.
  • Not Recommended For: Thick electrical cables, rebar, or soft metals like aluminum sheet.

Care:

  1. Cleaning: Wipe the cutting edges and body with a dry, lint-free cloth after each use to remove debris.
  2. Lubrication: Apply a light coat of oil (e.g., machine oil) to the joint mechanism periodically to ensure smooth operation and prevent rust.
  3. Storage: Store in a dry environment, preferably in a tool pouch or box, to protect the cutting edges from damage and corrosion.
  4. Avoid Overuse: Do not attempt to cut materials harder or thicker than specified, as this can damage the cutting edges.
