Works on bottom bracket cups too.

I love Shimano products. They are reliable and functional. No extra fuss, just perfect for good mountain bike parts. But man, they reinvent the tooling for everything. It’s a far more secure system than dubb but the sram interface works just fine! T25 as snd your golden. Maybe it’s the Japanese engineering. Just like Honda, Shimano makes everything just slightly better every generation. Also requiring slightly different tools…. Oh well! Now I have a new tool!
