Abstract : Drilling super duplex stainless steel (SDSS 2507) is challenging because of its high strength and poor thermal conductivity, which lead to excessive heat generation during machining. In conventional flood cooling, the generated heat is not sufficiently dissipated, and prolonged exposure to cutting fluids can pose health risks to operators. Cryogenic cooling, particularly using liquid nitrogen (LN?), offers an effective alternative for machining hard-to-cut materials. This study evaluates the dri
