Drilling is a process of making hole in a solid body with the help of multipoint cutting tool. Here to improve the life of tool, in order to minimize the production cost, to increase surface roughness different types of coating are applying over it, that coating soft/hard/ soft+ hard. Tool selection depends upon nature of drilling; dry, with coolant. This paper gives review of different coating techniques and its effectiveness by measuring deviation in hole diameter, surface roughness, and wear measurement. A back propagation neural network is preferred instead of radial basis neural network for the prediction of tool wear. It is considered that tool wear depends on cutting speed, feed, thrust force and torque.
