Fitter and Turner Interview Questions and Answers

Taping drill size refers to the size of the drill bit used to create threads for tapping holes.

• Taping drill size is determined by the size of the tap being used and the type of material being drilled.

• The drill bit size should be slightly smaller than the tap size to allow for proper thread engagement.

• For example, if using a 1/4-inch tap, a 7/32-inch drill bit may be used for softer materials, while a 15/64-inch drill bit may be used for harder materials.
