Klein Tools 63601 Compact Ratcheting Cable Cutter

The Klein Tools 63601 cuts up to 1000 MCM aluminum (500 mm2), 600 MCM copper (300 mm2), and communications cable up to 2-1/16 inches (52.4 mm) in diameter. Those are three different ceilings, so check which conductor you are cutting before you size the job to the tool: a 750 MCM copper feeder is past its copper rating even though it is well under the aluminum number.

No. Klein specifically warns against cutting steel or ACSR with the 63601. The blades are hardened steel sized for aluminum and copper conductors and communications cable, and putting steel strand through them will damage the cutting edges. For ACSR you need a cutter rated for it.

It is not. The 63601 has plastic covered handles with hand guards for grip and comfort, but Klein states plainly that the tool is NOT insulated and that plastic-dipped or slip-on handles are not intended for protection against electrical shock. De-energize the conductor, and wear approved eye protection when cutting. If you need an insulated cutter, look for a tool rated to 1000V VDE.

Yes, that is how the 63601 is built to work. The ratcheting mechanism is operated one-handed so your other hand can hold and position the conductor for a square cut. A quick release lever opens the blades from any point in the stroke, so you can pull the cable back out mid-cut, and a patented two-step ratchet cuts with fewer strokes than a single-step mechanism.

The 63601's ratcheting mechanism clamps the cable while it shears, which gives a straight cut with no burrs or sharp edges, so the conductor goes into a lug or compression connector without filing. That is the main reason crews pick a ratchet cutter over a hacksaw or bolt cutter, which deform and splay the strands.

Order Klein Tools 63601. That is the manufacturer part number for the compact ratcheting cable cutter with red handles; it ships as a single tool with no separate size or finish choices to specify.
