[0014] Optionally, chamfered surfaces are provided on both sides of the top of the cutter head.
[0015] Optionally, a side wall at one end of the drill body is provided with a chip removal groove, and the chip removal groove is spiral.
[0016] It can be seen from the above technical solutions that the embodiments of the utility model have the following advantages:
[0017] 1. The utility model is a multifunctional drilling drill bit for composite materials, which adopts a chip cleaning mechanism. When the drill body rotates, the blades can be driven to rotate, thereby driving the air flow to blow away the powdered chips around the hole, so that the drilling personnel can observe the hole conveniently and the manual cleaning step is omitted, making the drilling efficiency higher.
[0018] 2. The utility model is a multifunctional drilling drill bit for composite materials, which adopts a chamfered inclined surface design. Such a design can prevent the drill bit from being easily offset during drilling positioning, thereby achieving a better positioning effect.
[0019] 2. The utility model is a multifunctional drilling drill bit for composite materials, which adopts a filter screen design. Such a design can prevent particles from falling on the blades through the vent holes and prevent particles from being blown into the holes.
