Air Compressor spares & accessories: :

Each CAE Rock Drill is made with great precision keeping in mind the smallest details so that it performs with the greatest reliability and power. Each spare part of the rock drill is made using only the best raw material and accurately machined on CNC Machines. These are perfectly heat treated and ground with the closest tolerance that are required for the best performance in the rock drill.

Just any other part will not do. Because you can not be sure of the quality, the material used, heat treatment and most important the tolerances, hence no substitute can ever be efficient or reliable for your Hava Rock Drill.
