Best Cable Cutter for Electricians

The 63050 is Klein's standard-issue high-leverage cable cutter and the model most electricians mean when they say "Klein cable cutters." Klein publishes three separate ratings for it: 4/0 AWG aluminum, 2/0 AWG soft copper and 100-pair 24 AWG communications cable. Those numbers matter, because the aluminum and copper limits are not the same. Copper is harder, so the tool tops out two sizes lower on copper than it does on aluminum.

The curved shear jaws pull the conductor into the cut rather than pushing it out, which is why the finished end stays round instead of flattening into an oval. That saves time at the lug. At 9-1/2 inches the tool still fits a pouch, though it is a full-size plier, not a pocket cutter. Klein is explicit that it must not be used on steel, ACSR or any hardened wire, and cutting those will notch the edges permanently.

The 48-22-6104 is Milwaukee's ratcheting ACSR cable cutter. The ratchet is the point: instead of one hard squeeze, you take a series of light strokes and the mechanism holds the progress between them, so a conductor that would defeat a shear cutter comes apart without a cheater bar. The ACSR rating means it is built to handle the steel-reinforced overhead conductor that will destroy a copper-and-aluminum-only tool.

Check Milwaukee's published capacity chart for the exact conductor you are cutting, because the ratings differ between copper, aluminum and ACSR of the same nominal size. What this tool is not is an armored cable cutter. BX and MC armor needs to be slit, not sheared, and shearing it drives the cut steel edge into the conductors inside.

Channellock's 911 is an 11 inch shear-type cable cutter for copper and aluminum. The extra handle length is where the value sits: leverage scales with handle length, so a longer cheap cutter often out-cuts a shorter expensive one on the same conductor. Owner feedback is consistent that the jaws stay sharp as long as they only ever see soft metal.

The trade-off is bulk. Eleven inches of handle needs swing room, and in a tight junction box or a loaded panel you will find yourself reaching for something shorter. Like every shear cutter here, it is a copper and aluminum tool only. Steel, ACSR, screws and nails will notch the edges and the notch never comes out.

Knipex publishes capacity in metric, which trips up US buyers: 70 mm² multi-strand works out to roughly 2/0 AWG, and the 20 mm diameter limit is about 0.79 inches over the conductor. Inside that envelope it is the cleanest cutter here. The jaws are precision ground and the strands come apart square rather than splayed.

At 8 inches it is genuinely usable one-handed in a panel where an 11 inch cutter cannot open. Do not buy it as your only cable cutter if you regularly pull 4/0 aluminum feeders, because you will be at the top of its range every time. Buy it as the cutter that lives in the pouch for everything up to 2/0.

This entry corrects the most common mistake in cable cutter shopping. Armored cable is not cut with a shear-type cable cutter. A rotary armor cutter clamps the cable, and a crank turns a shallow blade that slits one turn of the spiral steel so the armor twists off. The conductors underneath are never touched.

Shearing BX or MC with a plier-style cutter flattens the armor and drives the cut steel edge inward against the insulation, which is exactly the fault that shows up later as a ground fault. Set the blade depth so it just breaks through the armor, run the crank, and snap the slit section off. Deburr or fit an anti-short bushing before you pull the conductors through.
