Abstract
The utility model relates to a screw groove type diamond drill bit, comprising a bit 1, a steel body 2, and a connecting head 3. Diamond particles and metal powders, after being mixed homogeneously, are sintered in a powder metallurgical process, forming the bit 1. The bit 1 and the steel body 2 are sintered together or welded together. The inner wall of the steel body is provided with helical grooves. The utility model solves the defects on the existing diamond drill bit is difficult to remove chips and is slow in drilling speed when being infixed with water, provides a diamond drill bit which removes chips smoothly and easily and has a quick drilling speed, and can be used to drill and process various brittle and hard materials.
Description
Technical field
The utility model relates to a kind of diamond bit, particularly a kind of spiral goove slot type diamond bit, and the boring that can be applicable to various crisp and hard materials is processed.
Background technology
In the prior art, the boring machining tool of crisp and hard material mostly adopts diamond bit, and when having water to creep into, ubiquity chip removal difficulty, rate of penetration wait not enough slowly.
The utility model content
The purpose of this utility model is to overcome the defective of prior art, spiral groove by steel body inwall is to the driving of cooling water, thereby provide a kind of chip removal smooth and easy, the diamond bit that rate of penetration is fast is specially adapted to the boring of various crisp and hard materials and adds the water that has in man-hour and creep into.
The technical solution of the utility model is: a kind of diamond bit comprises cutter head 1, steel body 2, adaper 3.Cutter head 1 is mixed after the powder metallurgical technique sinter molding by diamond particles and metal dust.Cutter head 1 and steel body 2 sintering or welded together, steel body 2 inwalls have spiral groove.
The beneficial effects of the utility model are: solved existing diamond bit chip removal difficulty, rate of penetration waits defective slowly, provides a kind of chip removal smooth and easy, and the diamond bit that rate of penetration is fast can be used for the boring processing of various crisp and hard materials.

The specific embodiment
Figure of description is an enforcement optimal way of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
As shown in the figure: comprise cutter head 1, steel body 2, adaper 3.Cutter head 1 is mixed after the powder metallurgical technique sinter molding by diamond particles and metal dust.Cutter head 1 is with steel body 2 sintering or weld together.Steel body 2 inwalls have spiral groove, can drive the current route, accelerate water velocity, improve the chip removal effect, and the working position to cutter head 1 produces a kind of impulse force simultaneously, reduces to creep into resistance, accelerate rate of penetration.
Claims (1)
- A kind of diamond bit, comprise cutter head (1), steel body (2), adaper (3), cutter head (1) is mixed by diamond particles and metal dust after the powder metallurgical technique sinter molding, cutter head (1) and steel body (2) sintering or welded together, it is characterized in that: steel body (2) inwall has spiral groove.
