How they're used: Thread cutting oil (thread making) and tapping (“grooving”) fluid lubricate, and dissipate heat, from the tool and workpiece, and remove chips during the cutting process. Ideally, they have good anti-weld properties to prevent the build-up of metal on the tool, and good corrosion control qualities.
The job of a good thread cutting oil or tapping fluid is to maximize the yield of parts per tool, while keeping thread quality high and consistent. The best products have lower viscosity, so that chips and contaminants flush easily away from the workpiece, control rancidity, and leave parts and machines “clean,” and free of sticky residues.
Thread cutting speed always plays a role in determining the best fluid to use; chip loading and the projected service life for cutting inserts are also important factors.

Castrol Variocut C Moly-Dee Cutting Fluid
This high performance thread cutting and tapping fluid improves threading accuracy, extends tool life, and improves surface finishes. Variocut C Moly-Dee is ideal for aluminum, titanium and steel, and is especially effective on difficult-to machine metals such as stainless steel and aerospace alloys.
Moly-Dee Cutting Fluid is non-chlorinated, with outstanding thermal and chemical stability. This resistance to breakdown allows closer tolerances and provides smoother, more accurate threads. EP additives promote optimum metal cutting performance and improved surface finishes.
Pro-Chem Pro Draw 722 Thread Cutting / Tapping Fluid
This high-performing, all-metal tapping and thread cutting lubricant was designed for High Pressure Lubrication Its chlorinated wax/oil gel formula clings to taps and tooling and withstands extremely high temperatures.
Pro Draw 722 is well-suited to almost every machining operation, including heavy-duty forming, threading, gear cutting, CNC tapping, external broaching, blind hole tapping, peck drilling and reaming, and extruding. It eliminates chipping and galling and greatly reduces tool breakage. It is virtually odorless. Pro Draw 722 is used as received by dipping or flooding, and can be diluted with mineral oil or mineral spirits for less demanding applications.
