I'm looking for a cheap source of cutting fluid.
I want something to use manually when turning on the lathe for the finishing cut. At the moment I'm using Rocol RTD, which works great but is expensive - $30 for 500ml, $200 for 5l.
I'm told RTD is a sulfur based cutting fluid and is a good general purpose cutting fluid. I just watched some lathe DVDs and the operator used a similar liquid, but used it more abundantly than I do.
Does anyone know of a cheaper similar product? I'm not really sure what is available or if that is the going price?
Thanks,
Frank
