Drilling is a separation process to create round holes into a material through chip removal. A distinction is made between blind hole drillings and through hole drillings. A core hole must be bored to cut a thread into the hole. Core holes have specific sizes which correspond to the taps. You can find these sizes in each tap table as it’s absolutely necessary to stick to it.
