Abstract
The utility model discloses an auger bit with lubricant inlet holes. The auger bit with the lubricant inlet holes comprises a bit body, the upper portion of the auger body is provided with a handle portion for clamping, the lower portion of the bit body is a working portion, the working portion comprises a guide portion on the upper portion and a cutting portion on the lower portion, a plurality of spiral chip pockets are formed in the surface of the outer side of the guide portion, and the plurality of lubricant inlet holes are evenly formed in the circumference of the upper end of the guide portion and are communicated with the upper ends of the chip pockets. The auger bit with the lubricant inlet holes solves the problem of lubricant addition of an auger bit in a using process through the lubricant inlet holes, is simple and convenient, and affects neither usage nor working strength of the auger bit, thereby being very practical.
Description
Technical field
The utility model relates to a kind of fluted drill, particularly a kind of spiral bit with lubricating oil entrance hole.
Background technology
Fluted drill in use need to be in its outer surface coating lubricating oil, and in collection process, also needs coating lubricating oil, and is placed in special-purpose tool box, avoids collision.Generally, when fluted drill is no, coats lubricating oil and take in again in tool box still eaily, but in the process of using, will add lubricating oil or a thing of relatively requiring great effort, need to quit work, even the drill bit of fluted drill be taken off and could be added.
Utility model content
It is very inconvenient that the utility model technical issues that need to address are that fluted drill in use adds lubricating oil.
For solving the problems of the technologies described above, the utility model provides a kind of spiral bit with lubricating oil entrance hole, comprise drill body, described drill body top is the shank for clamping, bottom is operate portions, described operate portions comprises the guide part on top and the cutting portion of bottom, on the outer surface of described guide part, be provided with a plurality of spiral chip pockets, on the circumference of described guide part upper end, be evenly provided with a plurality of lubricating oil entrance holes, described lubricating oil entrance hole communicates with described chip pocket upper end.A kind of spiral bit with lubricating oil entrance hole of the present utility model, is provided with lubricating oil entrance hole, and lubricating oil entrance hole is led in chip pocket, so just can in the situation that not dismantling drill bit, from lubricating oil entrance hole, lubricating oil be imported, until cutting portion; In the process of drill bit work, can in lubricating oil entrance hole, store lubricant grease, lubricant grease can progressively melt in the progressively rising of temperature of diamond bit, after melting, infiltrates chip pocket, finally imports to cutting portion.A kind of spiral bit with lubricating oil entrance hole of the present utility model, by arranging of lubricating oil entrance hole, solved the problem that fluted drill in use adds lubricating oil, simple and convenient, neither impact is used, do not affect the working strength of fluted drill yet, very practical.
As optimal technical scheme of the present utility model, the diameter 2-5mm of described lubricating oil entrance hole.The diameter of lubricating oil entrance hole can not be excessive, large can affect fluted drill working strength, the while can not be too little, little bad processing, and affect passing through of lubricating oil.
Wherein, described chip pocket is 2, and corresponding described lubricating oil entrance hole is also 2.
A kind of spiral bit with lubricating oil entrance hole of the present utility model, by arranging of lubricating oil entrance hole, solved the problem that fluted drill in use adds lubricating oil, simple and convenient, neither impact is used, do not affect the working strength of fluted drill yet, very practical, and can not cause the waste of lubricating oil; And except storing lubricant grease in lubricating oil entrance hole in the process of using at fluted drill, in income tool box, also can in lubricating oil entrance hole, store lubricant grease, because the time that lubricant grease can be preserved is longer than lubricating oil, the drill bit that is applicable to often not use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view;
Wherein, 1-drill body, 2-shank, 3-operate portions, 4-guide part, 5-cutting portion, 6-chip pocket, 7-lubricating oil entrance hole.
The specific embodiment
Below in conjunction with accompanying drawing, describe optimal technical scheme of the present utility model in detail.
As shown in the figure, a kind of spiral bit with lubricating oil entrance hole of the present utility model, comprise drill body 1, described drill body 1 top is the shank 2 for clamping, bottom is operate portions 3, described operate portions 3 comprises the guide part 4 on top and the cutting portion 5 of bottom, on the outer surface of described guide part 4, be provided with two spiral chip pockets 6, on the circumference of described guide part 4 upper ends, be evenly provided with two lubricating oil entrance holes 7, described lubricating oil entrance hole 7 communicates with described chip pocket 6 upper ends, the diameter 2-5mm of wherein said lubricating oil entrance hole 7.
A kind of spiral bit with lubricating oil entrance hole of the present utility model, is provided with lubricating oil entrance hole, and lubricating oil entrance hole is led in chip pocket, so just can in the situation that not dismantling drill bit, from lubricating oil entrance hole, lubricating oil be imported, until cutting portion; In the process of drill bit work, can in lubricating oil entrance hole, store lubricant grease, then, in the process of drilling bit high-speed rotary, due to the rising of temperature, lubricant grease can progressively melt, and after melting, infiltrates chip pocket, finally imports to cutting portion.A kind of spiral bit with lubricating oil entrance hole of the present utility model, by arranging of lubricating oil entrance hole, solved the problem that fluted drill in use adds lubricating oil, simple and convenient, neither impact is used, do not affect the working strength of fluted drill yet, very practical.The diameter of lubricating oil entrance hole can not be excessive, large can affect fluted drill working strength, the while can not be too little, little bad processing, and affect passing through of lubricating oil.
A kind of spiral bit with lubricating oil entrance hole of the present utility model, by arranging of lubricating oil entrance hole, solved the problem that fluted drill in use adds lubricating oil, simple and convenient, neither impact is used, do not affect the working strength of fluted drill yet, very practical, and can not cause the waste of lubricating oil; And except storing lubricant grease in lubricating oil entrance hole in the process of using at fluted drill, in income tool box, also can in lubricating oil entrance hole, store lubricant grease, because the time that lubricant grease can be preserved is longer than lubricating oil, the drill bit that is applicable to often not use.
