Best Ratcheting Cable Cutters
A ratcheting cable cutter replaces a hacksaw and a lot of swearing when you need to get through thick copper or aluminum cable cleanly. The ratchet mechanism multiplies your hand force across several strokes, so a tool that fits your hand can slice through 500 kcmil copper without a cheater bar.
Quick answer
The Klein Tools 63607 Ratcheting Cable Cutter is the best overall pick for most US electricians because it cuts up to 600 kcmil copper and 750 kcmil aluminum with a proven, widely stocked design.

What Matters Most for This Category
Capacity is the first number to check, and it should be stated in kcmil for copper and aluminum separately, because a cutter rated for 500 kcmil copper is not automatically rated for the same aluminum size. Next comes handle geometry: a longer handle gives more leverage but will not fit in a crowded bag or a tight panel. Blade type matters too, since some cutters are meant for copper and aluminum only and will be damaged by steel or ACSR. Finally, look at whether replacement blades and the ratchet mechanism are serviceable, because a cutter that cannot be re-bladed becomes scrap.

Klein Tools 63607 Ratcheting Cable Cutter
Top PickPros
- Cuts large copper and aluminum cable in repeated ratchet strokes instead of one hard squeeze
- Replacement blades are widely available through Klein and major retailers
- Well known in the US trade, so parts and warranty support are easy to find
Cons
- Bulkier than a plain cable cutter, so it takes up bag space
- Not intended for steel or ACSR
This is the cutter most US electricians picture when they think of a ratcheting cable cutter. The ratchet action lets you work through large conductors in stages, which matters when you are on a ladder or in a tight panel. Klein backs it with a broad US service network.
Greenlee 706 Ratcheting Cable Cutter
Heavy DutyPros
- Long handles give strong leverage on tough cuts
- Built for repeated professional use
- Greenlee is a long-standing US electrical tool brand
Cons
- Costs more than most homeowner-focused options
- Large size makes it awkward in tight spaces
Greenlee has been making cable cutting tools for the electrical trade for decades, and the 706 is aimed at crews doing repeated large-conductor work. The long handles trade portability for leverage. It is a professional-grade tool with a professional-grade price.
Klein Tools 63060 Ratcheting Cable Cutter
CompactPros
- Shorter profile fits into crowded panels and bags
- Still uses a ratchet mechanism for mechanical advantage
- Same Klein parts and support ecosystem as the larger model
Cons
- Lower maximum capacity than the full-size 63607
- Not a substitute for a heavy-duty cutter on very large cable
A smaller ratcheting cutter makes sense when your work is mostly branch circuits and moderate feeders rather than service entrance conductors. It keeps the ratchet advantage without the bulk. Check the stated capacity against the largest cable you actually expect to cut.
Southwire RCT-500 Ratcheting Cable Cutter
Value PickPros
- Lower entry price than premium trade brands
- Southwire is a familiar US electrical products brand
- Ratchet action still provides real mechanical advantage
Cons
- Fewer service options than the largest tool brands
- Capacity is below the biggest cutters on this list
Southwire is a name most US electricians already know from wire and cable, and this cutter brings ratcheting action at a friendlier price. It suits DIYers and apprentices who need occasional large cuts. Confirm the capacity rating against your specific cable size before buying.
Klein Tools 63606 Ratcheting Cable Cutter
Aluminum ReadyPros
- Rated for large aluminum conductors as well as copper
- Ratcheting action reduces hand fatigue on big cuts
- Part of a well-supported US tool line
Cons
- Overlaps in price with the higher-capacity 63607
- Still not rated for steel or ACSR
Aluminum feeder and service cable is common in US residential and light commercial work, and this model is aimed at that job. The ratchet lets you cut in stages rather than forcing one hard squeeze. Compare its stated capacity to the 63607 if you also handle large copper.
Milwaukee 48-22-6100 Ratcheting Cable Cutter
Brand MatchPros
- Fits naturally into a Milwaukee-heavy tool kit
- Ratcheting mechanism for reduced hand strain
- Widely stocked in US home centers and online
Cons
- Not the highest capacity option in this category
- Price sits above budget-focused alternatives
Milwaukee's entry into ratcheting cable cutters appeals to crews already standardized on the brand. It covers common copper and aluminum cable sizes with a ratchet action. If you are not brand-loyal, compare capacity and price against the Klein and Greenlee options first.
Ideal 35-078 Ratcheting Cable Cutter
BudgetPros
- Lowest typical price among the ratcheting options here
- Ideal is an established US electrical tool brand
- Ratchet action still beats a manual cutter on large cable
Cons
- Lower capacity than the top picks
- Fewer retail stockists than the biggest brands
Ideal has supplied the electrical trade for a long time, and this cutter is the budget entry point for ratcheting action. It handles common cable sizes without the premium price. Check the exact capacity rating, since budget cutters often top out sooner than full-size models.
Who Should Avoid the Top Pick
Skip a ratcheting cable cutter if your work is almost entirely small branch-circuit wire, since a good pair of lineman pliers or a compact cable cutter will be faster and cheaper. Also avoid any cutter rated only for copper and aluminum if you regularly deal with steel or ACSR, because you will damage the blade and possibly the ratchet.
Before You Buy
Measure the largest conductor you actually expect to cut and compare it to the cutter's stated kcmil capacity for copper and aluminum separately. Check that replacement blades exist for the model, confirm the handle length fits your bag and the spaces you work in, and read owner feedback about how the ratchet holds up after months of use.
FAQs
What size cable can a ratcheting cable cutter handle?
It depends on the model. Many full-size ratcheting cutters are rated up to roughly 600 kcmil copper and 750 kcmil aluminum, while compact models top out lower. Always check the manufacturer's stated capacity for your specific tool.
Can I cut steel or ACSR with a ratcheting cable cutter?
Generally no. Most of these tools are designed for copper and aluminum conductors only, and cutting steel or ACSR can damage the blade and the ratchet mechanism. Use a tool specifically rated for those materials.
Are replacement blades available?
For the major brands, yes. Klein, Greenlee, Milwaukee, Southwire, and Ideal all support their cutters with replacement blades through US retail and distributor channels, though availability varies by model.
Is a ratcheting cutter better than a manual cable cutter?
For large conductors, yes. The ratchet multiplies your hand force across several strokes, which reduces fatigue and lets you cut cable you could not cut with a single-squeeze tool. For small wire, a manual cutter is usually faster.
Do I need a ratcheting cutter for residential wiring?
Usually not. Most residential branch circuits use small conductors that a standard cutter or pliers handle easily. A ratcheting cutter earns its place on service entrance cable, feeders, and larger commercial work.
How much should I expect to pay?
Budget ratcheting cutters start around $70 to $110, mid-range models run roughly $120 to $180, and heavy-duty professional cutters can reach $200 to $280. Price generally tracks cut capacity and handle length.
Our verdict
For most US electricians and serious DIYers, the Klein Tools 63607 is the best balance of capacity, availability, and support. If you need maximum leverage for repeated heavy cuts, step up to the Greenlee 706, and if budget is the priority, the Ideal 35-078 gets you ratcheting action for less. Match the stated capacity to your largest conductor before you buy.
