Castrol Variocut™ C Moly Dee (previously called Moly Dee™ CF Tapping Fluid) is a high performance tapping fluid that improves threading accuracy, extends tool life, improves surface finishes and increases production. Variocut C Moly Dee is suggested for use on most metals, including aluminum, titanium and steel. It is especially effective on difficult-to machine metals such as stainless steel and aerospace alloys.
Used straight, Variocut C Moly Dee should be applied directly to the tool/workpiece interface from a spout-top can or other applicator. Used as an additive with straight cutting oils, it should be poured into a high agitation area in the machine sump. Add approximately one gallon of Variocut C Moly Dee to every ten gallons of conventional cutting oils. Variocut C Moly Dee is recommended for use on most metals including aluminum, titanium and steel. It can stain copper or copper alloys if not removed following use. This product is not water soluble and should not be mixed with water soluble oils or synthetic coolants. Consult your Castrol Sales Engineer for questions regarding compatibility.
