Hey guys. Hope everyone is doing well. I have a home built 4x4 CNC router that I'm running a 2.2kw Chinese spindle and a huanyang vfd with it. I am wanting a little more cutting power and wanting to jump up to a 4kw spindle. I've read some about the water cooled vs air cooled, round vs square, and just need a little guidance. Honestly I'd like to get away from the water cooled, but was wondering which square spindle would be a good choice. I've looked at the cheaper square ones on ebay and was wondering if they're any good. Thanks

I haven’t even purchased my CNC yet but I’m going to advise you that you get what you pay for. From what I have read, you should stay away from 3rd party vendors…… No or minimal support.
Do you know of any that I could look at?
Thanks
