What is a straight tap?

A straight tap is a type of cutting tool used in machining to create internal threads in a hole. It features a cylindrical shape with spiraled flutes that help remove material as the tap is turned into the workpiece. Straight taps are typically used for threading holes in softer materials and are designed to cut threads in a single pass without the need for a pilot hole. They are commonly available in various sizes and thread pitches to accommodate different applications.
