Description
Technical field
The utility model is related to carpenter's cutting tool technical fields, are a kind of self tapping Woodworking flat drills specifically.
Background technology
Old money Woodworking flat drill on the market mainly by positioning blade tip, main cutting edge, round bar and six side's handles, four part composition, is deposited
Application pressure, speed is needed to beat the hole bottom port burr that hardwood head speed is slow and the service life is low, is bored slowly, especially in drilling more
The defects of.
Utility model content
The purpose of this utility model is to provide one kind greatly improving cutting speed, and the self tapping carpenter to prolong the service life is flat
It bores.
In order to overcome above-mentioned defect in the prior art, the utility model adopts the following technical solution：
A kind of self tapping Woodworking flat drill, including chit drill mechanism, round bar and hexagonal handle, chit drill mechanism are located at below round bar, round bar
Below hexagonal handle；The chit drill mechanism is that flat and width is bigger than the width of round bar, which is provided with tapping screw thread point, master
Cutting edge and half notch, tapping screw thread point are located at below main cutting edge, and half bottom of the gap is main cutting edge, and half notch is equipped with cross
Sword and Zhou Ren, Zhou Ren are located at main cutting edge outermost and are longer than the cutting edge of main cutting edge, and chisel edge, which is tightly attached on Zhou Ren, also is located at half
On the outside of notch.
Further, the chit drill mechanism is flat, and tapping screw thread point both sides, which are equipped with, tilts angle lap, is formed and disconnects screw thread
The tapping screw thread point of line.
Further, the chit drill mechanism, round bar and hexagonal handle form brush and sac like self tapping Woodworking flat drill.
Further, half notch is right-angled trapezium, and main cutting edge is located in trapezoidal long side, and chisel edge is located at vertical edges
On.
Design is scientific and reasonable for self tapping Woodworking flat drill provided by the utility model, is improved to positioning blade tip, and institute is increased
Penetration rate can be improved by disconnecting the tapping screw thread point of threaded line, and voluntarily chip and guiding chip removal, make drilling cutting process more save
Power is convenient and smooth, reduces cutting pressure applied, greatly improves drilling cutting speed, improve productivity, extends and use the longevity
Life.
Description of the drawings
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property
It puts, other drawings may also be obtained based on these drawings：
Fig. 1 is a kind of self tapping Woodworking flat drill embodiment schematic diagram of the utility model；
Fig. 2 is the drill body enlarged diagram of Fig. 1 self tapping Woodworking flat drills；
Fig. 3 is the part schematic side view of self tapping Woodworking flat drill；
In attached drawing：1- chit drills mechanism；2- round bars；3- hexagonal handles；11- tapping screw thread points；12- main cutting edges；13- half is lacked
Mouthful；14- chisel edges；15- weeks sword；16- tilts angle lap.
Specific implementation mode
The utility model is described in detail below in conjunction with attached drawing and specific embodiment, herein showing with the utility model
Meaning property embodiment and explanation are used for explaining the utility model, but are not intended to limit the scope of the present invention.
As shown in Figure 1 to Figure 3, a kind of self tapping Woodworking flat drill, including chit drill mechanism 1, round bar 2 and hexagonal handle 3, chit drill mechanism
1 is located at 2 lower section of round bar, and round bar 2 is located at 3 lower section of hexagonal handle；The chit drill mechanism 1 is width of the flat and width than round bar 2
Greatly, tapping screw thread point 11, main cutting edge 12 and half notch 13 are which is provided with, tapping screw thread point 11 is pyramidal structure, and positioned at master
Below cutting edge, half notch 13 and chit drill mechanism 1 are all chamfered transitions, and half notch, 13 lower section is main cutting edge 12, half notch 13
It is equipped with chisel edge 14 and all swords 15, all swords 15 are located at 12 outermost of main cutting edge and are longer than the cutting edge of main cutting edge 12, chisel edge 14
It is tightly attached on all swords 15 and also is located at half notch, 13 outside.
As the improvement of above-described embodiment scheme, the chit drill mechanism 1 is flat, and 11 both sides of tapping screw thread point, which are equipped with, inclines
Bevel grinding angle 16 forms the tapping screw thread point 11 for disconnecting threaded line.
As the improvement of above-described embodiment scheme, the chit drill mechanism 1, round bar 2 and hexagonal handle 3 form brush and sac like self tapping wood
Work chit drill.
As the improvement of above-described embodiment scheme, half notch 13 is right-angled trapezium, and main cutting edge 12 is located at trapezoidal
In long side, chisel edge 14 is located in vertical edges.
Surface treatment mode visual user needs, and such as polishes, sandblasting, blacks, and electricity is chanted, the surface treatment modes such as titanizing, shape
At sealer.
In conclusion the self tapping Woodworking flat drill of the utility model is mainly by the tapping screw thread point 11 of disconnection threaded line, master cuts
Cut sword 12, round bar 3 and 15 4 part of hexagonal handle composition improve positioning blade tip, the self tapping of the increased disconnection threaded line of institute
Screw thread point 11 can improve penetration rate, voluntarily chip and be oriented to chip removal, make the more laborsaving convenience of drilling cutting process and smooth, subtract
Pressure applied is cut less, greatly improves drilling cutting speed, is improved productivity, is prolonged the service life.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
