Brownells Universal Do-Drill™ is a premium cutting oil formulated to enhance tapping, drilling, and cutting operations on various metals, including heat-treated steels, molybdenum, and stainless steel. Its non-evaporating nature ensures consistent lubrication throughout the machining process, reducing friction and wear on tools. This cutting oil is particularly beneficial for chambering and boring jobs, as well as serving as a coolant for lathe, mill, and shaper work.
By maintaining its lubricating properties without requiring continuous application, Do-Drill™ follows the tap or drill into the workpiece, ensuring smooth and efficient operations. Gunsmiths and machinists rely on this oil to extend tool life and improve finish quality on precision work. The 1-gallon container provides a substantial supply—a little goes a long way, making it an economical choice for serious tooling operations despite its premium quality.
