  • It has good cooling ability
  • It will cause only slight staining of ferrous metals
  • It will not cause sticking or gumming

This stuff works great! 04/13/2020 3:37:44 PM

I used this while boring a 2" hole in a 3" deep hole. Finished surface improved greatly over other cutting oil.

Great for reaming threading and tapping. 08/17/2019 9:15:57 PM

I use this for cutting chambers, threading, and other reaming functions. Sticks very well to parts. I bit pricey compared to other dark fluids but it is a quality product.

My Cutting Oil Replacement 11/15/2018 5:01:13 PM

I bought this cutting oil to replace some of the other oils I was using to keep my tooling cool and extend the life of them. Even though a thicker viscosity, this meets the metric and happy to have it. This is ideal for cutting gun barrel chambers and threading. Something for the gunsmith inventory.

Very Good For Drilling 04/08/2017 1:04:47 AM

Helps form good chips and makes drilling faster and easier. The drills are cooler after drilling with vipers venom than without. You can actually feel a difference (with a drill press or mill or lathe). You can feel it take less pressure for the drill to cut and for nice chips to form. I have not used it with end mills or with a lathe but you should still definitely get this.
