Naruto has enough of the TB chakra sealed within himself to be essentially a beacon for them to meet, if he truly desires more of their chakra all that is required is for kuruma to contact them telepathically (which he can do whether or not naruto has their chakra). Also naruto using the TB chakra does not make them his tool, is kuruma his tool? No he befriended kuruma just like he did the other bijus they will always be willing to help him but knowing naruto's personality he will probably never ask them for help especially with full kuruma.

PS: Asking them for help against momoshiki would not make much sense given momoshiki's ability to absorb chakra, naruto was already more powerful than momoshiki with full kuruma alone and he had sasuke and the other Kages to help also.
