When we talk about handheld drills, there are several power tool options and choosing the right one can significantly improve the drilling process. Before selecting the tool, let’s understand the main terminology used and main processes in the drilling world and their meanings:
Drilling: making a brand new hole in a workpiece
Boring: enlarging the hole
Reaming: giving a finishing touch to the hole
Countersinking: cutting a conical (V shaped) cut into a manufactured object

The step process is the most common in the industry and consists of using a different process until you reach the final hole diameter expected. An example is when a customer wants to drill a 1/2” hole diameter. He starts to drill at 1/4”, drills again in a larger hole diameter, and when it’s closer to the final diameter, it is possible to ream.
Note that this process has several steps (stages) and for each step, the customer usually needs a complete set of drilling machines and cutting tools.
