Many of our gunsmith customers have praised this product as our best for tapping, drilling, and cutting heat-treated steels, moly, and stainless. It is highly effective for chambering and boring and is also an excellent coolant for lathe, mill, and shaper work. By reducing tool costs, it can speed up production in your shop on a daily basis. It is a non-evaporating solution that doesn't require steam application for 99% of jobs. This solution travels with the tap or drill during work, saving you time and money. In fact, we have heard stories where four holes for a mount have been drilled and tapped using DO-DRILL™, and the tap remained sharp enough for future use. Considering the high price of taps presently, you can't afford NOT to use it.
