[0010] By adopting the above technical scheme, the drill bit portion of the fixed hole drill bit can drill a fixed diameter hole or ream a fixed diameter hole. When reaming is needed, the deeper the conical head of the knife handle is inserted into the plug-in slot, the farther the cutting surface of the telescopic reaming tool head mechanism moves out of the through hole. At this time, the size of the reaming can be determined by the depth of the knife handle, without replacing the entire knife, greatly facilitating the operator, solving the phenomenon of damage to the cutter due to large resistance of one-time drilling, greatly improving the service life, and the scale can be engraved on the outer side wall of the knife handle according to the reaming size generated by the descent of the knife handle, greatly facilitating the operator to observe.
