Abstract
The utility model discloses a trapezoidal diamond bit tool bit, including the tool bit body, the tool bit body is trapezoidal circular arc sheet structure, and tool bit body one end is thick, and the other end is thin. The utility model discloses a trapezoidal diamond bit tool bit welds on the drilling rod with thin one section in the course of the work, cuts with thick one end, and the gap of cutting out is big, does not influence the drilling rod promptly and gets into downtheholely, and the tool bit both sides also can not with by the friction of cutting the object, and the drilling resistance that significantly reduces to improve and creep into efficiency.
Description
Technical Field
The utility model relates to a diamond bit field, concretely relates to trapezoidal diamond bit tool bit.
Background
The shape and size of the present diamond bit tool bit have a lot of but the face of boring and the face of weld thickness all are the same, in order to make the drilling rod easily go into in the drilling general, the thickness of drill bit should be greater than drilling rod thickness measure 1-3mm promptly the hole that drills out the diameter ratio drilling rod 1-3mm, the equal thick drawback about this kind of cutting end face is in, really play the cutting action is the terminal surface, the tool bit side plays the rubbing action with the object of being bored in the drilling bit drilling process, there is the resistance to influence drilling rate. The utility model discloses make the tool bit trapezoidal, one end is thick, and one end is thin, works as cutting end thick one end, and thin one end is connected with the drilling rod as the welding end, and this trapezium structure tool bit is in the course of the work, cuts with thick one end, and the gap of cutting out is big, does not influence the drilling rod promptly and gets into downtheholely, and the tool bit both sides also can not cut the object friction with being cut, and the drilling resistance that significantly reduces to improve and creep into efficiency.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a trapezoidal diamond bit tool bit to solve the problem among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a trapezoidal diamond bit tool bit, includes the tool bit body, the tool bit body is trapezoidal circular-arc, and tool bit body one end is thick for cutting end, and the other end is thin for the welding end.
Preferably, the cutting end of the cutter head body is 0.5mm-1mm thicker than the welding end.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a trapezium structure tool bit is in the course of the work, with thick one end cutting, and the gap of cutting out is big, does not influence the drilling rod promptly and gets into downtheholely, and the tool bit both sides also can not with by the friction of cutting the object, and the drilling resistance that significantly reduces to improve and creep into efficiency.
