VIPER'S VENOM CUTTING OIL
A superior high sulfur cutting oil. Specifically formulated for cutting all ferrous metals, tapping, threading, and reaming. Vipers Venom works extremely well when threading or reaming Stainless Steel rifle barrels due to its extreme lubricity factor and cooling properties.
This is the same cutting oil we use when machining with high speed steel on gun parts here at Chambers Custom.
