Tool Review – eBay Ratchet Cable Cutters

For the latest big project, replacing the battery bank on the boat with 5 brand new 200Ah Yuasa heavy duty flooded lead acids, I’m going to need to make many short links from heavy battery cable to connect all 5 batteries into a parallel bank.
Cutting cable as big in diameter as a good sized thumb is difficult at best. In the past I’ve used a hacksaw, but it doesn’t do a very clean job, especially as the cut nears the end – strands get ripped from the cable by the relatively coarse blade & this reduces the current carrying capacity.
Over to eBay again netted a pair of ratchet-type heavy duty cable cutters for £30. These are rated to cut cable up to 240mm² or 600MCM.

The cutting head on these snips is massive – cutting through cable up to 35mm in diameter takes some force. The ratchet mechanism is used to get a large mechanical advantage to force the cutters through the copper, without having to resort to more expensive & complex mechanisms such as hydraulics. (Hydraulic cable cutters do exist, but cost a small fortune & are totally over-rated for the job).

Overall the tool seems to be well made, the handles are Vinyl dipped to make them more comfortable, which certainly helps when applying a large amount of force. Running a file over the cutters themselves reveals they’re actually hardened – unusual for cheapo Chinese tools.
