conical tip can heat the pad and wire together and still have a small space to feed the solder nicely.
i have used the main 3 types a lot.
i started with an Antex iron for many years - they only have a wedge shape tip.
then i got a xytronics iron for a couple of years and used a "screwdriver" style tip.
now i use T12 conical for almost everything.
btw, i get the tips from banggood.
i got the TS-D24 from Banggood together with my TS100. That's the smallest chisel tip sold for the TS100.
My TS100 came with the TS-B2 conical tip.
Two days ago i ordered the KSGER T12 STM32 soldering station. (the mini one without a power supply).
That station has way more tips to choose from..
i asked the seller to send me the T12-D12 with the station.. And i bought the T12-D16 XA High Grade.
According to the Hakko site there is one more size that is smaller hahaha.. T12-D08 that one is so small it looks like a conical tip

The price difference between the regular T12 tips vs the high grade is €3 so the regular cost around €3 and the high-grade ones cost €6.
btw a TS100 tip costs between €7 to €9..
