CNC threading insert – difference between partial and full profile
When you select a CNC threading insert, you need to be aware of whether to choose a partial profile or a full profile insert.
A thread actually has a radius or flat at the root, and a radius at the crest. A Partial profile insert finishes only the root of the thread, and does not touch the crest. The same partial profile insert can be used to cut threads with any pitch, with a common thread angle (e.g., 60 degree). Insert cost is therefore reduced, and so is the inventory of different inserts required.
A Full profile insert finishes the complete thread profile – the root and the crest. Each thread pitch of a particular standard requires a different insert. It gives you better dimensional accuracy, and a well finished thread with no burrs.
