The cutting tool used affects the ability to machine the workpiece. Therefore, the shank that needs to be gripped plays a crucial role in the process. It is therefore prudent to know what length of the tool needs to be gripped. On top of this, there are other important factors such as the use of polished shanks, cleaning of the shank and the tool holder which reduce friction. Moreover, it is important to consider the tolerance of roundness and diameter of the cutter shank. These tolerances should be 25 millionths and ISO h6 respectively.
