Our Most Popular Drilling, Machining, Tapping And Cutting Oil

Many of our gunsmith customers have told us this is the best product we've ever offered for tapping, drilling and cutting all types of heat-treated steels, moly and stainless. Excellent for chambering and boring jobs, a coolant for lathe, mill and shaper work – will speed production and reduce tool costs in your shop every day. Non-evaporating, does not require stream application for 99% of the jobs, it follows the tap or drill in the work. A moneysaver. We know of cases where all four holes for a mount have been drilled and tapped using DO-DRILL, and the tap was still sharp enough for future use. With taps as high priced as they presently are, you cannot afford NOT to use it.
