An adaptive drilling device for extracting bolts from a control rod drive mechanism (CRDM) in a boiling water nuclear reactor includes a guide assembly configured to align and secure drilling activity, a drill assembly configured to drive a drill bit into a CRDM bolt, and a thrust assembly configured to linearly and bidirectionally drive the drill assembly. The guide assembly has three guide plates and a pair of guide rods. The drill assembly includes a gear reduction drive motor, drill bearings, a drill bit, and a securing subassembly configured to secure the drill assembly to a first guide plate. The thrust assembly includes a thrust handle connected to the drive motor, a central plate nut, a lead screw running through the central plate nut and connected to the thrust handle, and a feed wheel connected to the lead screw.

An air control device includes an air suction port, air discharge ports, and an air control system. The air suction port takes in air. The air discharge ports discharge the taken-in air. The air control system discharges the air through the air discharge ports alternately for respective preset times. An air control method includes: taking in air; and discharging the air alternately through air discharge ports for respective preset times.
