Tapfree 2 Cutting Fluid

Tapfree 2 Cutting FluidClick for a Bigger Picture
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 fluids ship by GROUND ONLY !
These products are NOT available for export.
