Oil- or water-based fluids? Which coolant should be used in grinding processes when problems in terms of high forces, tool life, or subsurface damages occur? This paper will give an answer for the field of drill-flute and tap drill grinding under practical conditions. Parts of M2- and M3-steel were ground with different sintered corundum wheels and the influence that additives such as fatty acid and phosphorous in a mineral oil have on the grinding process and work results was analyzed. In addition, a comparison was drawn between results achieved using an ester based oil and an emulsion. This comparison focused on the grinding forces, the work surface roughness, and the thermal influence on the subsurface.
