Description

Multi-edge drill bit tool Technical Field The utility model relates to the technical field of drill cutters, in particular to a multi-blade drill cutter. Background Drill cutters are one of the common tools in many fields of machining, construction, geological exploration, etc. Conventional drill cutters typically employ single or double edge configurations, which have some significant drawbacks during the drilling process. If the prior art grants the patent with publication number CN214161657U, the invention discloses a compound screw thread drill bit, belongs to the field of drill bit devices, solves the problem that the procedure of drilling compound screw holes in the prior art is complex and unstable, and adopts the technical scheme that: A composite threaded drill bit comprises a first drill bit, a threaded knob and a second drill bit, wherein the diameter of the second drill bit is larger than that of the first drill bit, and the threaded knob is arranged at the tail of the first drill bit. However, when the drill bit is used, the single-edge drill bit tool is used for drilling, the number of cutting edges is limited, the cutting force is unevenly distributed, the drilling efficiency is easy to be low, and the use convenience is reduced. Disclosure of Invention In order to solve the technical problems, the utility model provides a multi-blade drill bit tool which improves the efficiency of drilling into objects, is convenient for linearly cutting the objects and improves the diversity. The utility model discloses a multi-blade drill bit tool, which comprises a drill rod, chip grooves, a side cutting assembly, first inclined planes, first cutting planes and second inclined planes, wherein the chip grooves are formed on the outer side wall of the drill rod, the two first inclined planes are oppositely arranged at the bottom end of the drill rod, the bottoms of the two first inclined planes form a first cutting plane shape, the two second inclined planes are oppositely arranged at two sides of the first cutting planes respectively, an included angle of 50 degrees is formed between the two second inclined planes and the two first inclined planes respectively, the side cutting assembly is arranged on the outer side wall of the two first inclined planes, the side cutting assembly is used for increasing the cutting capacity of the two first inclined planes, the drill rod is driven to rotate by external equipment, the drill rod is firstly contacted with an object to be cut through the first cutting planes, the object is drilled through the rotation of the bottoms of the first cutting planes, the side cutting assembly cuts two side objects of the two first inclined planes along with the first cutting planes continuously going deep, the area of the bottoms of the first cutting planes is reduced, the efficiency of the object drilling is improved, and meanwhile, the included angle between the first inclined planes and the second inclined planes is increased, the first inclined planes and the two first inclined planes are respectively, the two first inclined planes and second inclined planes are respectively, the first inclined planes and second inclined planes and inclined planes are respectively arranged, the first inclined planes and second inclined planes and second inclined planes, the inclined planes and inclined plane and the planes are respectively.
