Most of the lubricants pose a potential risk to the environment. There is an urgent need and development of low cost, environmental friendly alternatives. In machining processes, lubricants play multiple roles, apart from lubricating, the fluid acts as a cutting oil too and its other purposes include increasing tool life, smoother cutting action, better chip removal and improved surface finish. Traditionally mineral oils, cutting oils, mixtures of mineral + cutting oils and chemicals are used in different proportions along with additives. Through this paper, a practical case study on drilling, tapping and reaming for an industrial use on stainless steel 316 grade manifold blocks, using different lubricants has been elaborated. Some improvements in surface roughness have also been noticed. The study presents an innovative approach, using a natural-organic source that can be easily disposed of without causing any harm; additionally, its fragrance motivates and energizes the morale and ambiance of the work area under consideration. The roughness average values using coffee, as the lubricant gave better results (improvement from 5 to 11%) than other oils used in the experiments.
