Water has several functions when sharpening tools with Tormek's water-cooled sharpening systems. It keeps the steel cool so that it does not lose its hardness, steel particles and dust from the grindstone are absorbed so that they are not inhaled. The water tank for T-4 is suitable for the Tormek machine models with a 200 mm grinding wheel: Tormek T-4, Tormek T-3 and Tormek 1200. Defective water tanks can simply be replaced with a new one.
