18/4 AWG Shielded CNC Wire (50FT) — Flexible Stranded Shielded 18-Gauge 4-Conductor Cable for Stepper Motors, CNC Machines, NEMA Motors, VFD Spindles, CNC Routers, 3D Printers and More!

The cable is good quality, and I had no issue soldering it to aircraft connectors. I do not find the overall stiffness to be an issue, I think it will last just fine for the use I expect from my CNC in a hobbyist-use situation. If you are using your machine heavily, for commercial use, then possibly you would need something more flexible; for me it works just fine.In addition, there was a personal note from the vendor along with a small pack of Twizzlers - nice touch!

Not much more to say - it's shielded wire that does exactly as described and for a reasonable price.

The cable proved an unexpected challenge to locate and thankfully this vender had it. I've been looking for a quality shielded 4 conductor cable to be used in a HVAC data line application. This cable meets the bill and then some. The jacket is tough and protective of the 100% shield with a pure stranded copper drain wire. Each conductor is also pure copper and tightly twisted together. This cable is installed in a common cable ally with 24 runs of CAT6a data and multiple RG-8a medium RF power coax lines. No crosstalk whatsoever!I Highly recommend the vendor and this cable.

I was hesitant on buying this wire for my CNC project after reading the other reviews mentioning that it was too stiff for CNC. But I bought it anyway. I must say that the flexibility of this wire is fine, even 5 bundled together. Agree with the other reviews regarding its ability to take solder. It will solder, just not as well as nicely tinned wire. I would plan on using crimp connectors with this wire as it’s takes too much effort to solder a whole bunch of connections. 4 stars for the difficulty to solder, otherwise it works well for CNC.

This is some really good quality wire. It was just what I needed for the cnc spindle upgrade I was doing. This is a family based business, that really appreciates their customer’s. The delivery was very fast.

This wire is JUNK do not use it for your CNC machines. Number one reason is it is almost impossible to solder. Number two CCA does not take bending back and forth very many times because the aluminum will work harden and break. PLEASE PLEASE do not use this wire on your CNC machine that you put so much time into.

Replaced the spindle cable on my cnc router. Cable was a little stiffer than I had expected, but not so much that it would cause a problem. Internally, all wires were copper, unlike what was said in some of the other comments. One wire was difficult to solder. This is normally caused by oxidation. Cleaned the wire and used good fluxed solder and all was well.

Good quality shielded 18/4 cabling.
