Abstract
The invention discloses a twist bit with lubricating oil guide holes. The twist bit comprises a bit body; the upper portion of the bit body is a handle used for clamping, the lower portion is an operating portion, the operating portion comprises an upper guide portion and a lower cutting portion, the surface of the outer side of the guide portion is provided with a plurality of spiral chip grooves, and a plurality of lubricating oil guide holes are formed in the circumference of the upper end of the guide portion evenly and are communicated with the chip grooves. The twist bit has the advantages that the problem that lubricating oil is fed during usage of the twist bit is solved by adopting the lubricating oil guide holes, the twist bit is simple and convenient to use, the usage is not affected, the work intensity of the twist bit is not affected, and the twist bit is practical.
Description
Technical field
The present invention relates to a kind of fluted drill, particularly a kind of spiral bit with lubricating oil entrance hole.
Background technology
Fluted drill in use needs in its outer surface coating lubricating oil, and also needs coating lubricating oil in collection process, and is placed in special tool box, collision free.Generally, time fluted drill is no, coats lubricating oil and to take in tool box still eaily again, but the thing that lubricating oil or compares effort will be added in the process used, needs quit work, and even the drill bit of fluted drill are taken off and could be added.
Summary of the invention
It is very inconvenient that the technical issues that need to address of the present invention are that fluted drill in use adds lubricating oil.
For solving the problems of the technologies described above, the invention 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, and described operate portions comprises the guide part on top and the cutting portion of bottom, and the outer surface of described guide part is provided with multiple spiral chip pocket, circumferentially evenly be provided with multiple lubricating oil entrance hole in described guide part upper end, 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 invention, is provided with lubricating oil entrance hole, and leads in chip pocket by lubricating oil entrance hole, so just when not dismantling drill bit, can be imported by lubricating oil from lubricating oil entrance hole, until cutting portion; In the process of bit operation, can store lubricant grease in lubricating oil entrance hole, lubricant grease progressively can melt in the progressively rising of temperature of diamond bit, infiltrates chip pocket, finally import to cutting portion after thawing.A kind of spiral bit with lubricating oil entrance hole of the present invention, solves by the setting of lubricating oil entrance hole the problem that fluted drill in use adds lubricating oil, simple and convenient, neither affects use, does not also affect the working strength of fluted drill, very practical.
As the preferred technical solution of the present invention, 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, simultaneously 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 invention, the problem that fluted drill in use adds lubricating oil is solved by the setting of lubricating oil entrance hole, simple and convenient, neither affect use, the working strength of fluted drill is not affected yet, very practical, and the waste of lubricating oil can not be caused; And except lubricant grease can be stored in lubricating oil entrance hole in the process that uses at fluted drill, also lubricant grease can be stored in lubricating oil entrance hole when income tool box, because the time that lubricant grease can be preserved is longer than lubricating oil, be applicable to the drill bit infrequently used.

Fig. 1 is structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to sectional view;
Wherein, 1-drill body, 2-shank, 3-operate portions, 4-guide part, 5-cutting portion, 6-chip pocket, 7-lubricating oil entrance hole.
Detailed description of the invention
The preferred technical solution of the present invention is described in detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of spiral bit with lubricating oil entrance hole of the present invention, 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, the outer surface of described guide part 4 is provided with two spiral chip pockets 6, two lubricating oil entrance holes 7 are circumferentially evenly provided with in described guide part 4 upper end, described lubricating oil entrance hole 7 communicates with described chip pocket 6 upper end, 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 invention, is provided with lubricating oil entrance hole, and leads in chip pocket by lubricating oil entrance hole, so just when not dismantling drill bit, can be imported by lubricating oil from lubricating oil entrance hole, until cutting portion; In the process of bit operation, can store lubricant grease in lubricating oil entrance hole, then in the process of drilling bit high-speed rotary, due to the rising of temperature, lubricant grease can progressively melt, and infiltrates chip pocket after thawing, finally imports to cutting portion.A kind of spiral bit with lubricating oil entrance hole of the present invention, solves by the setting of lubricating oil entrance hole the problem that fluted drill in use adds lubricating oil, simple and convenient, neither affects use, does not also affect the working strength of fluted drill, very practical.The diameter of lubricating oil entrance hole can not be excessive, large can affect fluted drill working strength, simultaneously 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 invention, the problem that fluted drill in use adds lubricating oil is solved by the setting of lubricating oil entrance hole, simple and convenient, neither affect use, the working strength of fluted drill is not affected yet, very practical, and the waste of lubricating oil can not be caused; And except lubricant grease can be stored in lubricating oil entrance hole in the process that uses at fluted drill, also lubricant grease can be stored in lubricating oil entrance hole when income tool box, because the time that lubricant grease can be preserved is longer than lubricating oil, be applicable to the drill bit infrequently used.
