Preferably, the first drill 201 is mounted on the top end of the drill mounting seat 1 by welding.

Preferably, the drill bit mounting seat 1 is of a hollow structure, and an internal thread structure is arranged on the inner side surface of the drill bit mounting seat.

Preferably, the upper surfaces of the first drill 201 and the second drill 203 are both provided as fluted surfaces.

Preferably, the cross-sectional area of the circular hole 3 is equal to the cross-sectional area of the base 202.

Preferably, the first drill 201 is an alloy drill.

Preferably, the second drill 203 is a diamond drill.

The utility model has the advantages that: the internal thread structure on the round hole and the external thread structure on the base guarantee that the second drill bit that is worn and torn on the base can be changed in time, reduce cost to a certain extent, improve the efficiency of construction.
