The invention discloses a pilot type heading machine cutterhead for extra-hard rock excavation. The pilot type heading machine cutterhead for extra-hard rock excavation comprises a conical small cutterhead for advanced rock breaking and a planar large cutterhead which is arranged on the outer side of the small cutterhead and used for subsequent expanding excavation and rock breaking, the small cutterhead and the large cutterhead are provided with a plurality of first hobbing cutters and second hobbing cutters respectively, and the small cutterhead and the large cutterhead are further providedwith water spraying dust removing ports separately. According to the pilot type heading machine cutterhead for extra-hard rock excavation, a traditional rock breaking manner is changed, surface contact is changed into point contact, the rock breaking efficiency is overall improved, the construction period can be greatly shortened, cutterhead wear is reduced, and the problems that for traditional hobbing cutters, consumption is fast, frequent replacement is needed, the rock breaking difficulty is large, and the efficiency is low are solved.
