[What is a spiral tap?]
A cutting tap with grooves twisted so as to discharge chips in the direction opposite to the tap traveling direction (front side), making it ideal for machining "blind hole" threads. As it has good machinability, it is suitable for viscous materials (stainless steel, aluminum, copper, etc.). Also, as the discharge of chips is good, it is also suitable for machining. There are two types of materials, mainly HSS (= high speed steel) and carbide: HSS is tough and hard to break and carbide is abrasion resistant.
