Specific embodiment
For convenient for those skilled in the art understand that the utility model, practical to this below in conjunction with specific embodiments and the drawings
It is novel to be described in further detail.
Referring to figs. 1 to Fig. 4, a kind of brill that combined type molding brill includes cutter hub 1, connect with cutter hub provided by the utility model
First 2, and while being dismountable connection type between cutter hub, drill bit and cutter head with the tool bit part 3 of processing counter sink.Knife
Body 1 is ladder configuration, including the first ladder 11 and the second ladder 12, and be provided among cutter hub for installing drill bit first
Through-hole 13.Drill bit 2 includes shank 23 and the head 24 for work, and is connect by shank with cutter hub 1.When it is implemented, boring
The shank of head is inserted into first through hole.
Tool bit part 3 is provided with the second through-hole 31 for accommodating the first ladder of cutter hub 11, when the first ladder of cutter hub is inserted
When entering into the second through-hole, the end face of the close cutter hub of tool bit part and the ladder face contact of cutter hub, in the another of tool bit part 3
Endface is additionally provided with the blade 32 for cutting.In the present embodiment, blade uses alloy blade.
The first mounting hole 14 and the second mounting hole 15 for extending radially through cutter hub are provided on cutter hub 1, the shank 23 of drill bit 2 is set
It is equipped with and the first mounting hole and the matched third mounting hole 21 of the second mounting hole and the 4th mounting hole 22.Tool bit part be provided with
