Description
Technical field
This utility model relates to cutter field, a kind of ladder point high performance twist-drill.
Background technology
Drill bit uses and the cutter that parts carry out hole machined, and drill bit in the prior art typically has single-blade fluted drill
And multi-edge twist drill, most of fluted drills of the prior art rotate punching only in a direction, it is often necessary to change, with
Time drill bit great majority of the prior art be tip bit, penetration rate is fast not, and chip removal effect simultaneously is bad.
Summary of the invention
In order to solve the problems referred to above this utility model provide one can be rotated both clockwise and counterclockwise punching, punching speed
Degree block, the ladder point high performance twist-drill that chip removal simultaneously is effective.
It is achieved through the following technical solutions to reach the effect above this utility model:
This utility model is a kind of ladder point high performance twist-drill, and including drillstock and drill bit, drill bit is arranged on described drillstock
Front end, is provided with depressed part at drill bit low side, is provided with sword and lower sword, sets at bit upper end side on the drill bit of depressed part upper end
There are side rake, side rake to be arranged on and are provided with sword side bit upper end, side rake and the end face of drill end
It is connected, is provided with apex point portion in drill end centre position, the drill bit between apex point portion and end face is provided with groove, in apex point portion
Both sides, top are provided with apex point groove.
Further improvement of the utility model is: end face and the angle becoming 6-10 ° in horizontal direction.
Further improvement of the utility model is: depressed part low side caves inward 0.3-0.6 millimeter.
Further improvement of the utility model is: be provided with department of assembly in drillstock rear end, and department of assembly's thickness is 1.5-3 milli
Rice.
Further improvement of the utility model is: depth of groove is 0.2-0.5 millimeter.
The beneficial effects of the utility model are: the apex point portion being provided with at drill end carries out primary drilling, drill bit to parts
Hole is being carried out reworking, is improve trepanning velocity, the apex point groove that is provided with in apex point portion and drill end be provided with recessed
Groove is easy to chip removal, improves chip removal effect, and upper sword and lower sword are arranged on the both sides of a Flos Cannabis body, enable drill bit clockwise and inverse
Hour hands rotary drilling, cost-effective.
This utility model simple in construction, reasonable in design, punching can not only be rotated both clockwise and counterclockwise, reduce cost,
Improve process velocity, chip removal is effective simultaneously.
Accompanying drawing explanation

Rake 6 is connected with the end face 7 on drill bit 2 top, is provided with apex point portion 8 in centre position, drill bit 2 top, at apex point portion 8 and end face 7
Between drill bit 2 be provided with groove 9, be provided with apex point groove 10 in both sides, top, apex point portion 8, apex point portion 8 is arranged in drill bit 2 top
Between position, the parts needing processing are carried out preliminary hole machined get out aperture, drill bit 2 carries out reworking to aperture, gets out institute
The hole needed, improves process velocity, apex point groove 10 that the both sides in centre position, apex point portion 8 are arranged and be arranged on drill bit 2 upper end
Groove 9 can improve chip removal effect, it is preferred that groove 9 degree of depth is 0.2-0.5 millimeter, the depressed part 3 arranged in drill bit 2 lower end
The drill bit 2 of both sides is respectively equipped with sword 4 and lower sword 5 enables drill bit to be rotated both clockwise and counterclockwise boring up and down, increases drill bit 2
Service life, it is preferred that depressed part 3 low side caves inward 0.3-0.6 millimeter, end face 7 and the folder becoming 6-10 ° in horizontal direction
Angle can speed up the speed that aperture is processed by drill bit.
This utility model simple in construction, reasonable in design, punching can not only be rotated both clockwise and counterclockwise, reduce cost,
Improve process velocity, chip removal is effective simultaneously.
