Suggestions To Remove Connectors?

Hello all...Trying to figure out an easy way to remove the connectors on an 8-way coaxial splitter. The connectors are brass and the casing is aluminum.

Here's a link of what I'm talking about. (Regret link, can't attach picture).

DIRECTV 8-Way Wideband Splitter for SWM Satellite LNBs (SPLIT8MRV) from Solid Signal

The connectors are threaded, so it's possible to screw them off but trying to figure out if there's a tool that I can do this quickly & efficiently. I have a few hundred of these so if I can do quickly & efficiently, it might be worth it to separate.

Any suggestions would be helpful.

Hammer, hatchet, linesman plyers, and nut driver and Philips screw driver attached to an impact driver or drill. Advantage using cordless. I use one bit on the impact driver and the other on the drill.
