Review on 💧 Ridgid Dark Thread Cutting Oil - High Performance 1 Gallon Dark Pipe Threading Oil, Black by Jerry Frey

Not sure what the difference is between thread cutting oil and flat cutting oil but I like it. I mainly use it when drilling with a drill press. It's quite thick and sticky, but it can be smoky and greasy. However, the benefit is that it improves drilling, the tool stays cooler and the cut is faster. I noticed less digging and broaching. The best cutting oil I have ever used!
