Aluminum Metal Matrix Composites (AMMCs) are the well defined materials for marine, automobile, aerospace, defense, and sports industries, as they have high strength to weight ratio, and possess superior physical and mechanical properties compared to UN-reinforced alloys and traditional metals. However, the presence of abrasive reinforcements in the ductile matrix causes rapid tool wear and hence tool failure. This leads to an increase in machining cost, production time and poor quality of machined components. Among all traditional machining processes, drilling is one of the most important metal-cutting operations, comprising approximately 33% of all metal-cutting operations. Drilling processes are widely used in the aerospace, aircraft and automotive industries. Although modern metal-cutting methods have been improved in the manufacturing industry, including Electric Discharge Machining, Ultrasonic Machining, Electro Chemical Machining, Laser Beam Machining and Abrasive Jet Machining, conventional drilling still remains one of the most important machining processes. Among the cutting conditions which influence the drilling process, coolant is an important factor largely affects
