Quick answer: The Knipex Cobra 87 01 180 suits someone who needs a compact adjustable gripping tool often enough to justify paying for precise adjustment. It is not a universal replacement for spanners, smooth-jaw pliers or larger pipe tools. Its toothed jaws are a reason to buy it for grip, and a reason to avoid it on decorative finishes. This is a specification-led review, not a claim of hands-on testing.
Exact model and useful specifications
The model reviewed is 87 01 180, with non-slip plastic-coated handles, grey atramentised pliers and a polished head. Knipex identifies it with EAN 4003773022015; the associated ASIN is B000X4PU26. Check the complete number: other Cobra lengths, handle types and sets are different purchases.
Knipex's data sheet gives a weight of 170g, dimensions of 180 × 42 × 14mm and 18 adjustment positions. Stated capacities are 42mm pipe diameter and 36mm across nuts. The button sets the jaw opening, while a box-joint construction supports the mechanism. The gripping teeth are hardened to approximately 61 HRC. These are manufacturer specifications rather than independently measured results.
Why choose the 180mm size?
The main reason is a compact kit. A tool that fits your storage and reaches the job can be more useful than a larger one left elsewhere. Fine jaw adjustment may also let you set a more comfortable handle span than a basic slip-joint design. That does not establish that this size is right for every hand or every tight space: compare the dimensions with the clearance around the fitting you intend to reach.
The smaller size has a trade-off. It does not provide the same leverage or maximum opening as a larger tool. Buying it and then immediately needing a second pair for your normal work is false economy. Start with the dimensions of your actual jobs rather than assuming the middle of a product range is automatically the best choice.
Where it is the wrong tool
The toothed gripping surfaces can mark chrome, plated fittings and other finished surfaces. A correctly sized spanner or suitable smooth-jaw tool is often a better choice where appearance matters. Nor should a stated maximum jaw opening be mistaken for permission to apply unlimited force: the fastener or fitting may fail first.
The plastic coating on this model is a grip feature, not a verified electrical-insulation rating. Do not buy it as an insulated tool. This review also does not turn a general household tool into approval for gas or electrical work; use the correct equipment and appropriately qualified help for work outside your competence.
Pros and cons
- Pros: compact 180mm format, multiple adjustment positions, mechanical operation without batteries, and clearly documented capacities.
- Cons: toothed jaws can damage finishes, limited leverage compared with larger pliers, and a higher initial outlay than basic occasional-use tools.
Price evidence and how to judge value
On 12 November 2026, Power Tool World's page displayed £24.95 including VAT for this exact model. Delivery must be added where applicable; the page advertises free delivery over £50 with regional exclusions. This is an alternative retailer reference, not a verified Amazon price or a claim that it is the cheapest available.
Amazon's product page could not be accessed during our check. Its live price, seller, delivery and any discount remain unverified. Compare the same 180mm model as a single tool, not a multi-tool bundle or another handle variant. A crossed-out recommended price is less useful than the amount another reputable seller will actually charge, including delivery.
Cost of ownership and alternatives
There are no batteries or compulsory refills. The practical costs are purchase, storage, maintenance and eventual repair or replacement. Keep the tool clean and dry and follow the manufacturer's care guidance. We found no evidence establishing a lifespan for your use, so a lifetime cost calculation would be speculative.
If you need pliers once for a simple job, borrowing the correct tool can be better value. If you already own dependable water-pump pliers that fit the work, this purchase may add convenience without saving money. For frequent use, the important question is whether adjustment and grip solve a repeated annoyance. For finished nuts, consider an appropriate spanner or smooth-jaw pliers wrench; for larger pipework, first check the specifications of a larger tool.
Value verdict
This is a focused compact-tool purchase, not a must-have upgrade for every home. Buy it when you can name recurring jobs that fit its capacity and tolerate toothed jaws. Otherwise keep your existing tool or borrow one. Our bathroom repair planning guide follows the same principle: identify the job and materials before filling a shopping basket.
