The front end of the drilling and milling blade is provided with three drill points, one of the drill points is positioned at the central axis of the cutter body, and the other two drill points are symmetrically distributed on two sides of the drill point in the middle.
The drill point in the middle part is provided with two symmetrical cutting edges and a chisel edge positioned in the middle part, and the drill points on two sides are respectively provided with one cutting edge.
The front ends of the three drill points are positioned on the same plane vertical to the central axis of the cutter body.
The diameter of the front drilling and milling edge is 4.2 mm, and the diameter of the rear drilling and milling edge is 5.1 mm.
The drilling and milling blade is provided with more than two blades along the circumferential direction, and the chip discharge grooves are formed between the adjacent drilling and milling blades.
Compared with the prior art, the two-blade drilling and milling chamfer cutter of the utility model is provided with two drilling and milling blades with different diameter parts on the cutter body, and the chamfer blade is arranged at the rear part of the drilling and milling blade, so that holes with two different sizes can be drilled, or slotted holes with two different sizes can be milled, countersunk holes can be simultaneously processed when needed, the condition of cutter replacement can be reduced, the processing time can be effectively reduced, and the processing cost can be reduced; in addition, the drill point is provided with three, has special design's shape, has increased the quality of drilling to a great extent, can guarantee the smoothness in the hole after the drilling, does not have the flash in the hole.

fig. 2 is a left side view of the double-edged milling chamfer cutter of the utility model.
Detailed Description
The present invention will be described in further detail with reference to the following examples and accompanying drawings.
As shown in fig. 1, the utility model discloses a two sword bores mills chamfer sword includes: a blade 1 at the front and a handle 2 at the rear. The tool shank 2 is mainly used for being fixed on a drill chuck of a drilling machine. The front part of the cutter body 1 is provided with a drilling and milling blade 3, the front end of the drilling and milling blade 3 is formed with a drill point 6, and the rear end is also connected with a chamfer blade 5. The drilling and milling edges 3 and the chamfering edges 5 are respectively provided with more than two in the circumferential direction, and chip grooves 4 are formed in the side wall of the cutter body 1 between the adjacent drilling and milling edges 3 and are mainly used for discharging metal chips and the like generated in the machining process of workpieces.
The utility model discloses in, two parts that the diameter is different around drilling and milling sword 3 is equipped with, the diameter of anterior drilling and milling sword 31 department is less than the diameter of rear portion drilling and milling sword 32 department. In this embodiment, the diameter of the front drill edge 31 is 4.2 mm, and the diameter of the rear drill edge 32 is 5.1 mm. Therefore, the drilling and milling blade 3 can drill holes with two different sizes, and meanwhile, the drilling and milling blade 3 can mill slotted holes with two different sizes. Therefore, the condition of replacing the cutter can be reduced, the processing time can be effectively reduced, and the processing cost can be reduced.
The chamfering edge 5 is connected to the rear end of the rear milling and drilling edge 32, and the chamfering edge 5 is designed similarly to a conventional chamfering tool and is acted upon by the chamfering edge 5 when it is required to machine a countersunk hole.
As shown in fig. 1 and 2, in the utility model, the front end of the drilling and milling blade 3 is provided with three drill points 6, one of them drill point 6 is located the central axis position of the blade 1, and two other drill points 6 symmetric distributions are formed by extending forward the upper and lower both sides of the front end of the drilling and milling blade 3 at the drill point 6 both sides at the middle part. Wherein, the drill point 6 in the middle is provided with two symmetrical middle cutting edges 61 and a chisel edge 62 with a short middle tip, and the drill points 6 on both sides are respectively provided with a side cutting edge 63. In addition, the front ends of the three drill points 6 are positioned on the same plane perpendicular to the central axis of the cutter body 1. This is in contrast to conventional drills which are provided with only one drill tip and which consist of two cutting edges and a chisel edge. When drilling, the middle drill point drills the hole of the workpiece, the hole wall is cut through the side cutting edges 63 of the two points on the two sides in the drilling process, metal chips can be discharged out of the hole along the chip removal grooves 4 under the guiding action of the cutting force of the side cutting edges 63 on the two sides when chip removal is conducted, and through the special design, the smoothness of the hole after drilling is guaranteed, no burrs exist in the hole, and a good chip removal effect can be achieved.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
