We have temporarily removed these items from our catalog while we re-organize our inventory.
Tapfree 2 Cutting Fluid.
For all metals except magnesium.
Environmentally safe, water-based fluid.
Used for tapping, milling, drilling, etc.
Quickly penetrates to the cutting edge and reduces friction and heat generated during cutting.
Safer than chlorinated solvents or oils.
Intended to be used full strength (primarily through misting or direct application), and not in recirculators. The viscosity of these fluids makes pumping difficult.

Please note: these cutting and tapping fluids ship by GROUND ONLY !
These products are NOT available for export.
