Description
Technical field
The present invention relates to rapid steel tool technical field, and in particular to a kind of new high speed steel twist drill.
Background technology
High-speed steel is a kind of tool steel with high rigidity, high-wearing feature and high-fire resistance, also known as high-speed tool steel or high-speed steel, is commonly called as Bai Gang.High-speed steel is that Taylor F.W. and M. White in the U.S. formulated in 1898.
The processing performance of high-speed steel is good, and intensity and toughness are worked good, therefore is mainly used to manufacture complicated thin sword and impact-resistant metal cutting tool, can also manufacture high-temperature bearing and cold extrusion die etc..In addition to the high-speed steel produced with method of smelting, PM HSS is occurred in that again after 1960s, its advantage is that of avoiding the carbide segregation caused by smelting process production and causes mechanical performance to reduce and heat treatment deformation.
High-speed steel is often used as on hardware ＆ tools, with stronger hardness, is increased the durability of instrument, still, because the drill bit of fluted drill is easily damaged when in use, is caused integral replacing, compare waste, it would be highly desirable to improve.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of new high speed steel twist drill simple in construction, reasonable in design, easy to use, drill bit is convenient for changing, while also a saving cost, its practical performance is greatly enhanced.
To achieve the above object, the technical solution adopted by the present invention is：It includes staight shank portion, cutting portion, drill bit；The top in staight shank portion is provided with cutting portion, and the top of cutting portion is provided with drill bit；Described staight shank portion is integral type structure with cutting portion；Described cutting portion is detachable connection with drill bit；The lower end of described drill bit is provided with threaded connection post；The upper end of described cutting portion is provided with the threaded connection groove being engaged with threaded connection post；Described threaded connection post is equipped with fixed pin holes with being threadedly coupled on groove, and threaded connection post and threaded connection groove pass through fixed pin connection.
Described steady pin is arranged in the chip area on cutting portion.
The operation principle of the present invention：When bit damage, directly steady pin is taken out, drill bit is screwed off, the drill bit more renewed is convenient and practical.
After said structure, the present invention has the beneficial effect that：A kind of new high speed steel twist drill of the present invention, is convenient for changing drill bit, while also a saving cost, greatly enhances its practical performance, and the present invention has simple in construction, sets reasonable, the advantages of low manufacture cost.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, the required accompanying drawing used in embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, without having to pay creative labor, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the present invention.

Description of reference numerals：
Staight shank portion 1, cutting portion 2, drill bit 3, steady pin 4, fixed pin holes 5, threaded connection post 6, threaded connection groove 7.
Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Referring to as depicted in figs. 1 and 2, the technical scheme that present embodiment is used is：It includes staight shank portion 1, cutting portion 2, drill bit 3；The top in staight shank portion 1 is provided with cutting portion 2, and the top of cutting portion 2 is provided with drill bit；Described staight shank portion 1 is integral type structure with cutting portion 2；Described cutting portion 2 is detachable connection with drill bit 3；The lower end of described drill bit 3 is provided with threaded connection post 6；The upper end of described cutting portion 2 is provided with the threaded connection groove 7 being engaged with threaded connection post 6；Described threaded connection post 6 is equipped with fixed pin holes 5 with being threadedly coupled on groove 7, and threaded connection post 6 and threaded connection groove 7 are connected by steady pin 4.
Described steady pin 4 is arranged in the chip area on cutting portion 2.
The operation principle of the present invention：When drill bit 3 is damaged, directly steady pin 4 is taken out, drill bit 3 is screwed off, the drill bit 3 more renewed is convenient and practical.
After said structure, the present invention has the beneficial effect that：A kind of new high speed steel twist drill of the present invention, is convenient for changing drill bit, while also a saving cost, greatly enhances its practical performance, and the present invention has simple in construction, sets reasonable, the advantages of low manufacture cost.
It is described above, it is merely illustrative of the technical solution of the present invention and unrestricted, other modifications or equivalent substitution that those of ordinary skill in the art are made to technical scheme, without departing from the spirit and scope of technical solution of the present invention, all should cover among scope of the presently claimed invention.
