To determine the drill size for tapped holes, you typically refer to a tap drill size chart, which provides the recommended drill bit diameter based on the size and thread pitch of the tap. The general formula used is to take the nominal screw size and subtract the thread pitch to find the appropriate drill size. For example, for a 1/4"-20 tap, you would use a 7/32" drill bit. Always ensure to consider the material being tapped, as it may affect the final drill size choice.

The recommended pilot hole drill bit size chart for various types of screws and materials can vary, but generally, it is recommended to use a bit that is slightly smaller in diameter than the screw being used. This helps to create a pilot hole that allows the screw to be inserted easily without splitting the material. It is important to match the drill bit size to the specific screw and material being used to ensure a proper fit and secure connection.
