Is it possible to replace U shape grommet at the T-Joint of Yonex racket using degrommeting tool? If so, how?
You shouldn't need to use the grommet remover at all. I just take something flat (back of my thumb) and push it out. U grommets usually come off quite easily.
If the gromment is damaged or really stuck, a piler is handy, as you can pull it out from the curved portion.
