55 and 60 degree square threading are the two most common types of threading used in machining operations.

HSS (High Speed Steel) is a type of tool steel that is commonly used for cutting tools because of its ability to withstand high temperatures and wear. HSS is often used for threading operations because it can maintain its hardness at high temperatures and is less likely to dull or wear out quickly.

When selecting between 55 and 60 degree square threading, the choice will depend on the specific requirements of the application. 60 degree threading is more commonly used for metric thread forms, while 55 degree threading is more commonly used for unified thread forms.

In general, 60 degree threads are more widely used than 55 degree threads. However, both types of threads have their own advantages and disadvantages, and the selection will depend on factors such as the material being threaded, the thread pitch, and the required strength and durability of the thread.
