Keeps burs, drills, sawblades, gravers plus many other cutting and abrading tools working smoother and longer. Reduces heat build-up and friction to speed the cut. Easy and convenient to use. Leave it right on the bench and just dip or run the tool through the lubricant at regular intervals while working. Apply a small amount of lubricant to the wire and the opening. Handy 1 oz. push-up container.
