Best Cable Cutters for Copper and Aluminum Cable
Whether you are rewiring a panel, pulling service entrance cable, or trimming stranded copper on a job, a true cable cutter gives you a clean, round cut instead of the crushed, flattened end you get from lineman's pliers. Below are the cutters we would actually buy, picked on published cutting capacity, jaw design, and manufacturer specs rather than guesswork.
Quick answer
For most electricians and serious DIYers, the Klein Tools 63050 high-leverage cable cutter is the best all-round choice: shear-type jaws rated for 4/0 aluminum, 2/0 soft copper, and 100-pair 24 AWG communications cable. If you want the cleanest, lightest cut on smaller multi-strand cable, the Knipex 95 11 200 cable shear is the one to get.

Klein Tools 63050
Best OverallPros
- High-leverage design cuts large cable with modest hand force
- Shear-type jaws leave a round, uncrushed cable end
- Klein limited lifetime warranty against defects
Cons
- Not rated for steel, ACSR, or armored cable
- Plastic-dipped handles are basic compared with Journeyman grips
The 63050 is the cutter most US electricians picture when someone says "cable cutter." The jaws work by shearing rather than pinching, so the conductor keeps its round shape and slides straight into a lug or connector without needing to be reformed. Klein rates it for 4/0 aluminum, 2/0 soft copper, and 100-pair 24 AWG communications cable, which covers the large majority of residential and light commercial work.
The high-leverage pivot is the reason it feels easier than its size suggests: most of the effort goes into the cut rather than into squeezing the handles. What it is not is a general-purpose cutter. Steel wire, ACSR, and armored cable will nick or spring the blades, and those jobs need a bolt cutter, an ACSR cutter, or a rotary armored-cable tool instead.
Knipex 95 11 200
Best PrecisionPros
- Very clean cut with almost no strand splay
- Compact enough to live in a pouch
- Excellent fit and finish
Cons
- Costs more than comparable US-brand cutters
- Copper and aluminum only, no steel or ACSR
Knipex cable shears use a crescent-shaped blade that pulls the cable into the jaw as you close it, so the strands cannot slip forward and fan out. On fine-stranded flexible cable that difference is obvious, which is why these are popular with panel builders and anyone terminating a lot of ferrules.
At 200 mm it is smaller and lighter than the Klein 63050, and capacity drops accordingly to roughly 70 mm² multi-strand copper or aluminum, or about 20 mm cable diameter. That is close to 2/0 AWG, so it handles most branch circuit and control cable comfortably but is not the tool for 4/0 service conductors.
Klein Tools J63050
Best For All-Day UsePros
- Same jaws and capacity as the 63050
- Journeyman grips are noticeably kinder over repeated cuts
- Better handle retention with sweaty or gloved hands
Cons
- Costs more than the standard 63050 for identical cutting performance
- Slightly bulkier handles in a tight pouch
The J63050 is the Journeyman version of the 63050: identical shear-type jaws and identical 4/0 aluminum and 2/0 soft copper rating, with Klein's dual-material handles instead of plastic dip. If you are cutting a handful of cables a month, that upgrade is not worth the premium. If you are cutting all day, or working outdoors in the cold, it is.
Everything else applies exactly as it does to the 63050, including what it will not cut. Treat the two as one tool with two handle options and pick based on how much time your hands spend on it.
What to Check Before Buying Cable Cutters
Cutting capacity is the first thing to match, and it is quoted separately for copper and aluminum because copper is harder. A cutter rated for 4/0 aluminum will usually be rated for something smaller in soft copper, such as 2/0. Compare against the largest conductor you actually cut, not the largest one you can imagine cutting.
Jaw type matters more than most spec sheets suggest. Shear-type cutters slice past each other like scissors and leave a round conductor end. Bypass and pinch-style jaws crush the cable, which means extra work reshaping it before it enters a lug. For anything above about 6 AWG stranded, shear-type is worth insisting on.
Handle length and grip decide how the tool feels after the tenth cut. Longer handles give more leverage on heavy cable but take up more pouch space, and dual-material grips hold better than plastic dip when your hands are wet. None of this changes what the tool can cut, so decide capacity first and comfort second.
What About Heavy Gauge and Ratcheting Cutters
Above roughly 4/0, plain scissor-action cutters run out of leverage and you move to a ratcheting cable cutter, which takes several squeezes to work through 250 MCM and larger conductors. Both Klein and Knipex sell ratcheting models, and the important number to compare is the MCM rating for the conductor material you use, since aluminum and copper ratings differ significantly on the same tool.
Mistakes to Avoid When Buying Cable Cutters
The most common mistake is buying a wire stripper or a diagonal cutter and expecting cable cutter performance. Tools like the Klein 11055 are excellent wire strippers and cutters for 10 to 18 AWG solid and 12 to 20 AWG stranded wire, but they are not built to take a 2/0 conductor, and forcing one through will spring the joint.
Using a copper and aluminum cutter on steel wire, ACSR, or armored cable is the other reliable way to ruin a good tool. Those materials will nick the cutting edges, and once a shear-type jaw is nicked it never cuts cleanly again. Check the material list in the manufacturer's specification before every unfamiliar cut.
Finally, do not undersize. A cutter used at the very top of its range is slow, tiring, and hard on the blades, while the same cut on a slightly larger cutter is effortless. Sizing up one step costs a few dollars and saves the tool.
FAQs
Is the Klein 11055 a cable cutter?
No. The Klein Tools 11055 is a wire stripper and cutter for 10 to 18 AWG solid and 12 to 20 AWG stranded wire. It is a great tool for terminating branch circuits, but it is not rated for heavy multi-strand cable. For that you want the Klein 63050 or similar.
Can I use cable cutters on steel wire?
No. The cutters here are rated for copper and aluminum only. Steel wire, ACSR, and armored cable will nick the blades and are usually excluded from the warranty.
What is the difference between cable cutters and wire cutters?
Cable cutters have large shear-type jaws for thick multi-strand cable and leave a round end. Wire cutters and diagonal cutters are small pinch-style tools for individual solid or stranded conductors.
How do I maintain my cable cutters?
Keep the blades clean and dry, add a drop of light oil at the pivot occasionally, and never cut material the tool is not rated for. Nicks in a shear jaw are permanent.
Are Klein Tools cable cutters worth the money?
For regular electrical work, yes. Klein hand tools carry a limited lifetime warranty against defects in materials and workmanship, and the 63050 pattern has been a jobsite standard for decades.
What size cable cutter do I need for house wiring?
Branch circuit wiring at 14 to 10 AWG needs very little cutter, so almost anything on this list is enough. Size for the service entrance and feeder cable you handle instead, which is where 2/0 and 4/0 ratings matter.
Can I cut live wires with cable cutters?
No. Disconnect and verify dead first. These cutters are not insulated tools and are not rated for live work.
What does 4/0 aluminum, 2/0 soft copper mean?
It is a dual rating. The tool will cut up to 4/0 in the softer aluminum but only up to 2/0 in copper, because copper is harder. Always read the rating for the metal you are actually cutting.
Does 70 mm² mean anything in AWG?
Roughly 2/0 AWG. Knipex publishes metric cross-sections, so 70 mm² multi-strand is about 2/0, and 16 mm² is about 6 AWG.
Are longer cable cutters better?
Longer handles give more leverage, which helps at the top of the capacity range, but they are heavier and bulkier. Match length to the cable you cut most often.
Can I cut armored cable with a standard cutter?
No. MC and BX armor needs a rotary armored-cable cutter or a hacksaw. Putting it through a copper and aluminum shear will damage the jaws.
What does AWG mean?
American Wire Gauge, the US standard for conductor size. Lower numbers are thicker, and sizes above 1 AWG are written 1/0, 2/0, 3/0, and 4/0.
Our verdict
The Klein Tools 63050 is the cable cutter to buy for most people: shear-type jaws, 4/0 aluminum and 2/0 soft copper capacity, and a price that does not sting. Choose the Knipex 95 11 200 if cut quality on finer multi-strand cable matters more than raw capacity, or the Klein Tools J63050 if you cut cable all day and want the better grips. For 250 MCM and up, skip all three and buy a ratcheting cutter rated for your conductor material.
