Two useful implements for fashioning threads, the tap and the die, may be equivalent in some ways yet also hold several dissimilarities.
Threading and cutting capabilities can be found in two major tools – Taps and Dies. Both can be employed to stitch threads into a hole that’s already been created, or alternatively, to cut threads into a pre-formed workpiece. This can occur for either an internal or external threaded application.
Taps boast a pointed tip that permits effortless thread-cutting, while dies come with a flat edge that needs more precision to ensure suitable alignment before use.
Taps, crafted from high speed steel or carbide, are more resilient to wear-and-tear and offer the capability to successfully thread into harder materials. Comparatively, dies are crafted from tool steel and carry fewer risks of breakage but cannot always manage to create threads in difficult substrates.
Applying excessive torque to a tap can be disastrous, so it is necessary to be mindful of this when using one. Moreover, it is vital that the tap is well lubricated and stays in good condition, otherwise it could malfunction or get clogged up.
Selecting the appropriate die for a given job is the first requirement when embarking on a threading process. Fixed to a die holder, the die then needs to be affixed firmly to the workpiece, with secure clamping as an essential step. To cut the threads, the holder needs to be turned in order to accommodate this.
Those proficient in thread work know that having the appropriate tool makes all the difference, and when it comes to taps and dies, both are essential. It is true that their purpose is similar; however, there are several elements to take into account before selecting which of them to employ.
