Description
Technical field
The utility model is related to a kind of deep tooth single-blade from work(mechanical woodworking drill, available for nonmetallic materials such as timber, plastics
Upper drilling, belongs to carpenter's auger technical field.
Background technology
The deep tooth typically commonly used at present is cut from work(mechanical woodworking drill by screw thread apex point, two main cutting edges of correspondence, circumference
Sword, flute, drilling rod, drillstock composition overall structure.Because drill body structure is special, in use, its cutting moment of torque resistance
Greatly, user's labor intensity is high.
The content of the invention
The utility model carpenter's auger technical problem to be solved is：There is provided one kind can be adapted to drill gently under different working conditions
Hurry up, deep tooth single-blade that cutting moment of torque resistance is small from work(mechanical woodworking drill, to reduce labor intensity, be adapted to bore under different working conditions
The problem of hole, raising construction speed.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is to provide a kind of deep tooth single-blade from work(machinery wood
Work is bored, it is characterised in that including drilling rod, one end of drilling rod is connected with drillstock, and the other end of drilling rod is provided with screw thread apex point, single master
One end of the drill body of cutting edge and circumferential cutting edge composition, one end of main cutting edge and circumferential cutting edge is connected, main cutting edge with
Flute is provided between the other end of circumferential cutting edge；Screw thread apex point is located at the center of drill rod end, the circumference cutting
The relief angle of sword is 10 °, and the inclined angle of main cutting edge is 60 °；The depth of the chip area of circumferential cutting edge between cog be 6.19~
9.14mm.Base thickness degree is bored according to drill bit size specification and thickeies 3.25~6.65mm.
Preferably, it is fixedly connected between the screw thread apex point and drilling rod by interior hexagonal holding screw.
Preferably, the end of the drillstock is provided with drillstock clamping neck.
It is highly preferred that the drill body, drilling rod, drillstock are structure as a whole, drilling rod is provided with to match with interior hexagonal holding screw
The tightening screwed hole of conjunction.
The utility model has the advantages that：Single-blade drill body structure design, reduces cutting moment of torque power, to reduce labor intensity, carry
High workload efficiency.A sidetracking base thickness degree is thickeied, drilling smoothness caused by balance single-blade drill body structure design；Increase circumference cutting
Edge clearance angle and inclined angle, reduce borehole axial resistance；Circumference chip removal groove depth is increased, increases and holds bits rate, plug bits resistance is reduced
Power.；
