Abstract
The invention relates to a high-efficient sawtooth drill bit, which is characterized in that: a triangular or trapezoidal tooth slot is formed on the front face of a screw groove on a rotating direction of the drill bit; a steel mouth is in a sawtooth shape and is protruded; when in use, due to the protruded sawtooth, the common linear stressing of the plain end steel mouth is replaced with point type stressing in sawtooth shape, so that the stressing condition of the drill bit is greatly improved. The working efficiency of the drill bit is improved, the service life of the drill bit is prolonged, and the convenience and the practicability are realized.
Description
Technical field
The present invention relates to industrial goods, particularly a kind of zigzag drill bit that has.
Background technology
Present known drill bit is flat mouthful, the drill bit of flat mouthful shape in fact, and intensity is high, but sometimes; Under situation about having, for example, people are with drill bit perforate on high density plate material, but common bit speed is slow; The situation that also has drill bit to jump out can be damaged the surface of high density plate material, also has, in the drill steel plate; Common bit speed is slow, but also wants the edge of a knife of frequent abrasive drilling head, and application life is short.The speed of boring is slow, and the life-span is short, and people have also thought a lot of ways, improve constantly the material of drill bit, still can not fundamentally improve, and people post and hope that new technology can break through this bottleneck.
Technology contents
The present invention can effectively overcome above-mentioned deficiency, and a kind of jagged drill bit that has is provided.
The present invention is achieved in that the front at the silk groove of the direction of rotation of drill bit; Leave triangle or trapezoidal teeth groove; Make steel mouth indentation, and protrusion, the sawtooth of protrusion in use; Making common flat mouthful of steel mouth wire, stressed to become jagged point-like stressed, thereby greatly improve the force-bearing situation of drill bit.And then reach the work effectiveness that improves drill bit, and the purpose that prolongs the application life of drill bit, convenient and practical.
Description of drawings
Fig. 1 is a sketch map of the present invention
Among the figure: 1 drill bit shaft; 2 drill bits; 3 grooves; 4 teeth groove;
The specific embodiment
As shown in Figure 1: at an end of drill bit shaft 1; Triangle or trapezoidal teeth groove 4 are left in the front of the silk groove 3 of the direction of rotation of drill bit 2, make steel mouth indentation; And protrusion; The sawtooth of protrusion in use, making common flat mouthful of steel mouth wire, stressed to become jagged point-like stressed, thereby greatly improve the force-bearing situation of drill bit.And then reach the work effectiveness that improves drill bit, and the purpose that prolongs the application life of drill bit, convenient and practical.
Claims (3)
