Tool designed by using Trepanning Process is reckoned for its precise hole diameter. This specific method is a drilling process that involves generation of hole at the center of a tool. This drilling technique requires less time and its production cost is also low. This method is mainly followed for metal bars having large dimension. Tools made by adopting Trepanning Process are used for cutting of carbide. These tools are especially suitable for deep hole boring job. This specific drilling process requires less energy. This method is usually followed by honing or counter boring process. Provided tool is cost effective and is simple to handle.
