If the hole is created by a process called ‘boring’ or by a tool with a zero tip angle, the bottom of the hole will be flat. These two types of blind hole drilling are shown in the drawing below: You may use the prefix, suffix, subfix or superfix fields in the dimension to add additional text as needed.
