Boelube® is a specially formulated lubricant patented by Boeing Aerospace. Use it on drill bits, reamers, saw blades, taps & dies, boring tools, and any other application where smooth cutting action is required. The application of a small amount of Boelube, which is consumed in the metalworking process, will greatly improve tool life, surface finish, and hole quality. The high film strength, lubricity and unique polar properties are the key to its ability to provide superior lubrication. Boelube is completely safe: it is non-toxic, will not promote dermatitis, and does not leave any undesirable residue. 1 lbs (0.5Kg) shipping weight.
