Chesterton’s 395 Tapping Lubricant is a high quality petroleum based machining lubricant specifically designed for aluminum and other soft metals. It is a high performance cutting fluid that will not stain and darken such metals during machining processes.

395 Tapping Lubricant reduces friction at point of contact by depositing a protective oily film which clings to machine tools. Excellent dimensional control and smooth thread finish are achieved as tools and parts are kept cool and well lubricated. The active agents in 395 Tapping Lubricant bind the compound to working edges promoting its effectiveness deep into the cut. Chips are prevented from welding back to the parent metal behind the cutting point. As chips move freely, tool breakage from galling is eliminated.

Many tapping compounds are formulated with chlorinated hydrocarbons because they provide excellent cooling. However, these solvents can stain and darken metal especially aluminum. The high performance additive package used in 395 Tapping Lubricant will reduce friction and prevent heat build up to provide excellent dimensional control without use of chlorinated compounds. The product will treat the metal surface of parts to provide a superior, uniform finish.
