When you need to thread a hole, it may seem easiest to reach for the nearest right-size tap. After all, the threads will be identical in gage and will accommodate the type and size of external fastener threads. But even before drilling the hole, professional machinists consider the material being tapped, whether the hole is through or blind, and other variables before deciding whether to use a cut tap or a form tap.
