Abstract
The utility model relates to a rightward rotation drill tip which presents a rod body shape. The utility model comprises a drill handle part which is integrally formed and a drill head part, wherein the drill bit part is arranged at one end of the drill handle end. The drill bit part comprises a plurality of rightward rotation drill edges, a rightward rotation worm groove is respectively at the place between every two drill edges which are adjacent with each other and the rightward rotation worm grooves are arranged along the drill edges. The drill handle part and the drill head are respectively integrally formed, and the drill handle part presents a cylindrical rod body. Because the utility model is provided with the rightward rotation worm grooves, cooling liquid can be sufficiently supplied to the drill edges, particularly the tip ends of the drill edges, high heat generated by cutting can be quickly dropped off. The utility model has the advantages of high speed of chip removal, the decrease of sticky chips and adhering edges, the prevention of plastic deformation and long service life.
Description
Technical field
The utility model relates to a kind of dextrorotation bit, relates in particular to the high heat that a kind of cutting that leaves fast produces, and reduces sticking bits and adheres to sword, prevents plastic deformation, the dextrorotation bit of long service life.
Background technology
Bit is the indispensable instrument of every profession and trade borings such as building, machining, and bit divides from structure can be divided into the left side brill that is rotated counterclockwise (left-handed), and bore on the right side of turn clockwise (dextrorotation).The anti-wear performance quality of bit, cooling fluid whether can ample supply to drill lip, the chip removal speed whether direct the length in its service life.
Summary of the invention
The purpose of this utility model is to provide a kind of dextrorotation bit, and its high heat that cutting produces that can leave fast reduces sticking bits and adheres to sword, prevents plastic deformation, long service life.
For achieving the above object, the utility model provides a kind of dextrorotation bit, be a body of rod, it comprises an integrated drill shank and a bit head, this bit portion is located at an end of drill shank, this bit portion comprises the drill lip of some dextrorotation, offers a dextrorotation snail groove between these two adjacent drill lips, and this dextrorotation snail groove is along the drill lip setting.
This drill shank and bit head are integrated.
This drill shank is a cylindrical body of rod.
This bit portion comprises the above-mentioned drill lip on this dextrorotation bit body of rod of being located at of two dextrorotation, offers two above-mentioned dextrorotation snail grooves between these two drill lips.
This dextrorotation bit is made by the good high-speed steel of wearability.
This dextrorotation bit is divided into short sword type and long sword type.
The utlity model has following beneficial effect: owing to have this dextrorotation snail groove, cooling fluid can ample supply arrive drill lip, and especially therefore the tip of drill lip can leave fast and cut the high heat that produces; Have this dextrorotation snail groove, chip removal is fast, reduces sticking bits and adheres to sword, prevents plastic deformation, long service life.
Description of drawings
Fig. 1 is the front view of the utility model dextrorotation bit first embodiment.
Fig. 2 is the front view of another embodiment of the utility model dextrorotation bit
The specific embodiment
See also Fig. 1 to Fig. 2, a kind of dextrorotation bit is made by the high-speed steel that wearability is good, and integral body is a circular body of rod, and it comprises a drill shank 1 and a bit head 2, and this drill shank 1 and bit head 2 are integrated.
This drill shank 1 is a cylindrical body of rod, and its end is fixedly clamped on a drilling machine (figure does not show).
This bit portion 2 is located at the front end of drill shank 1, and the drill lip 22 that it comprises on the body of rod that is located at this dextrorotation bit of two dextrorotation offers two dextrorotation snail grooves 24 between these two drill lips 22.These two dextrorotation snail grooves 24 are provided with along drill lip 22.Smear metal can discharge along this dextrorotation snail groove 24.
This dextrorotation bit is applicable to the deep hole machining of diameter more than 3 times, is widely used in tensile strength and reaches 1000N/m
2Deng processing such as steel, stainless steel, cast irons.
This dextrorotation bit is divided into short sword type and long sword type.
Owing to have this dextrorotation snail groove 24, cooling fluid can ample supply arrive drill lip 22, and especially therefore the tip of drill lip can leave fast and cut the high heat that produces; Have this dextrorotation snail groove 24, chip removal is fast, reduces sticking bits and adheres to sword, prevents plastic deformation, long service life.
