In turning process, the heat is generated due to friction, and this heat can be removed by application of cutting fluid. The cutting fluid serves as an agent to cool the cutting tool and provides lubrication between the tool-chip and tool-work piece interface, but it also produces environmental pollution and other operator health issues. To overcome this issue, some research works are focused with different types of textured surface on rake surface of turning cutting tool inserts for sustainability improvement. The present work is focused on application of nano-powder mixed vegetable oil (coconut oil) as coolant for textured cutting tool inserts in turning process. The results of textured inserts with Nano Powder Mixed Cutting Fluid (NPMCF) are compared with solid lubricant embedded textured inserts. The result is concluded that improved machining performance with NPMCF as coolant than solid lubricant textured tool inserts. Textured inserts with NPMCF facilitates infiltration, spreadability and absorption, also provides effective lubrication and cooling function. The results of the investigation revealed that textured inserts with NPMCF is important to obtain the improved machining performance and sustainability
