Abstract
The utility model discloses a kind of diamond thin-wall drill bit rectangle cutter tooth, include one piece of circular arc cutter tooth body, circular arc cutter tooth body one end is welding ends, welding ends has rectangular recess to be connected with seamless steel pipe, the circular arc cutter tooth body other end, for cutting end face, cuts on end face and has rectangular recess.The beneficial effects of the utility model are that frictional force reduces, and the speed that makes it is fast, drilling depth is many, the life-span is long, stable working, and operating efficiency is high, and has saved the cost of material.
Description
Technical field
The utility model relates to the cutter field of cutting high hardness material, specifically belongs to diamond thin-wall drill bit rectangle cutter tooth.
Background technology
Diamond thin-wall drill bit rectangle cutter tooth is a kind of important component part of cutting high hardness material cutter, and diamond bit is stable working in cutting high hardness material, can also reuse.General diamond thin-wall drill bit rectangle cutter tooth rubbing surface is comparatively large, and penetration rate is slow, and inefficiency, when operation, stationarity is poor compares effort, works dumb.
Utility model content
In order to overcome above-mentioned prior art Problems existing, the utility model provides a kind of diamond thin-wall drill bit rectangle cutter tooth, and not only friction area is little, and penetration rate is fast, and operation horizontal stability is good, saves material cost, can increase work efficiency.
The technical solution of the utility model is as follows:
A kind of diamond thin-wall drill bit rectangle cutter tooth, include one piece of circular arc cutter tooth body, circular arc cutter tooth body one end is welding ends, welding ends has rectangular recess and is connected with seamless steel pipe, the circular arc cutter tooth body other end, for cutting end face, cuts on end face and has rectangular recess.
The utility model end face be welded on seamless steel pipe has a rectangular recess, weld time can better more fast and stable be welded on steel pipe, cut end face and also have a rectangular recess, when contacting with the face of being cut, contact surface is little, frictional force is also just little, during such processing operation, the penetration rate of cutter tooth can be faster, and advanced depth can be darker.
The beneficial effects of the utility model are that frictional force reduces, and the speed that makes it is fast, drilling depth is many, the life-span is long, stable working, and operating efficiency is high, and has saved the cost of material.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of diamond thin-wall drill bit rectangle cutter tooth, include one piece of circular arc cutter tooth body 1, circular arc cutter tooth body 1 one end is welding ends 2, welding ends 2 has rectangular recess 3 to be connected with seamless steel pipe, circular arc cutter tooth body 1 other end, for cutting end face 4, cuts on end face 4 and has rectangular recess 5.
The utility model Novel diamond thin-wall drill bit rectangle cutter tooth is formed by diamond machined system of closing, if figure mono-end face is welded on seamless steel pipe, and other end directly contacts cutting material, when cutting, contact area is less, frictional force makes it to reduce, penetration rate accelerates, thus improves operating efficiency.
