Description

X-shaped drill point edge drill bit

Technical Field

The utility model relates to the technical field of machining, specifically be X type drill point sword drill bit.

Background

Stainless steel is a difficult-to-machine material, and has poor cutting performance, which causes great friction to the drill bit, so that the drill bit for drilling stainless steel must be made of heat-resistant and wear-resistant material and the cutting edge of the cutter must be sharp, so that it is not practical to use a common twist drill. A drill bit for stainless steel is generally used for drilling stainless steel.

At present, 3C stainless steel generally adopts the ordinary drill point of two swords, and in the cutter course of working, wearing and tearing are fast, and the easy tipping, the tool changing is more frequent, influences production efficiency and manufacturing cost simultaneously.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an X type drill point sword drill bit to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: an X-point drill comprising: cutting portion, neck and handle of a knife portion, handle of a knife portion one end processing has the neck, the neck is kept away from handle of a knife portion one end processing and has the cutting portion, the cutting portion is kept away from neck one end processing and has the main cutting edge, the cutting portion is close to main cutting edge one side middle part processing and has vice cutting edge, the processing of cutting portion outer wall has the chip groove, the leading sword is the X shape.

Further, a drill point is formed in the center of the main cutting edge.

Furthermore, the cutting part, the neck part and the tool shank part are made of wear-resistant hard alloy materials.

Furthermore, the neck part and the handle part are in arc transition connection.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a main cutting edge that sets up, vice cutting edge and handle of a knife, realized when X type drill point sword drill bit uses, main cutting edge through the X shape, thereby the cutter can disperse the drill point cutting force and reach the purpose of adding man-hour fine protection drill bit drill point, the main cutting edge of X shape is wear-resisting simultaneously, the cutter is longe-lived, the actual work blade is separately, reduce the tool changing and transfer the sword time, shorten the assistance-time, reduce work piece processing cost, more effectual raising efficiency and quality, cooperate its alloy material, ultra-high wearability has, X type drill point sword drill bit simultaneously, the drill bit adopts RLTILMAC technology, cooperation lathe coolant oil, the blade effect of surely going out is better, the size stability of processing out.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: an X-point drill comprising: cutting portion 1, neck 2 and handle of a

knife portion

3, 3 one end processing of handle of a knife portion has

neck

2, 3 one end processing of handle of a knife portion has cutting portion 1 is kept away from to neck 2, neck one end processing has main cutting edge 101 is kept away from to cutting portion 1, cutting portion 1 is close to main cutting edge 101 one side middle part processing and has vice cutting edge 102, the processing of 1 outer wall of cutting portion has chip groove 103, main cutting edge 101 is the X shape, main cutting edge 101 central authorities are formed with the drill point, cutting portion 1, neck 2 and handle of a knife portion 3 are wear-resisting carbide material, neck 2 is circular arc transitional coupling with handle of a knife portion 3.

The working principle is as follows: when X type point drill bit uses, through the main cutting edge 101 of X shape, thereby the cutter can disperse the point cutting power during processing and reach the purpose of processing fine protection drill bit point, simultaneously the main cutting edge 101 of X shape is wear-resisting, the cutter is longe-lived, the actual work blade is part, reduce tool changing and accent sword time, shorten the assistance-time, reduce work piece processing cost, more effectual raising the efficiency and quality, cooperate its alloy material, have super high wearability, X type point drill bit simultaneously, the drill bit adopts R0LL00MATIC technology, cooperation lathe coolant oil, the blade effect of surely cutting is better, the size of processing out is stable.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
