A thread chaser is used to clean and restore damaged or dirty threads vs. a tap or, die which cuts threads.
A tap is a tool, a tap can cut or clean the threads of a bolt hole, there are differant diameters and thread pitch, a dye is the opposite of a tap it cuts or cleans the threads of a bolt.
In general a female thread is cut with a tap. A male thread is cut with a die.
Cutting a thread on a shaft
STI stands for "Screw Thread Insert." When tapping a thread with an STI tap, you're typically preparing the hole to receive a threaded insert, commonly known as a helicoil or thread insert, which helps reinforce or repair damaged threads. My Recommendation 𝐡𝐭𝐭𝐩𝐬://𝐰𝐰𝐰.𝐝𝐢𝐠𝐢𝐬𝐭𝐨𝐫𝐞𝟐𝟒.𝐜𝐨𝐦/
A UNJF-3B tap is a type of threaded tap used to create UNJF (Unified National Fine Thread) screws with a 3B tolerance class. The "UN" designates the Unified National thread series, while "JF" indicates a specific thread form with a 60-degree angle and a rounded crest. The "3B" refers to the tolerance grade, which specifies the allowable deviation from the nominal dimensions for internal threads. This tap is commonly used in aerospace and high-precision applications where tight tolerances are crucial.
Taps and dies are used to thread . A tap threads a hole and a die threads a rod.
Assuming you mean "thread tap", it is for cutting new threads in a hole.
Taps and dies are used in threading. To make an internal thread, you drill a hole smaller than the thread width, then slowly screw a 'tap' into it cutting a thread very slowly. -For an external thread, you choose a rod or bolt larger than the final thread, then screw a hard, threaded disc down onto it.

It has got to be tapered to get in a fresh hole. Then you can finish it up with a square one to tap out the bottom of the hole.
