Abstract
The utility model relates to a machine used auger bit, which comprises a bit body and a bit handle connected into a whole body, wherein the bit body is provided with a main cutting edge, a minor cutting edge and a spiral groove, the spiral groove is used for containing and discharging drilled sawdust, and the head part of the bit body is provided with a spiral tip; the spiral tip is propped on wood and can advance and retreat automatically by the rotation power of an electric drill without the need of propelling force, and the bit body is also provided with scale marks; and the bit handle is a regular six-sided cylinder. Because the auger bit is provided with the main cutting edge and the minor cutting edge, drilling can be kept stable in high-speed cutting, sawdust discharge is smooth due to the structure of the spiral groove, and a drilling wall of a drill hole is ensured to be smooth.
Description
Technical field
The utility model relates to a kind of wood working tool, belongs to the boring bar tool field.
Background technology
The instrument that is applicable to drilling timber in the prior art mainly is two kinds of common fluted drill and flat-wing drillers, common fluted drill has only drill body and drillstock to constitute, the head of drill body is taper, the hole that gets out in actual use is bright and clean inadequately, and, make stock-removing efficiency low because cutting resistance is big, can not advance automatically, require great effort very much during use, and also there is the chip removal situation of difficult in these two kinds of brills.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, provide a kind of simple in structure, can cut, the machine Zhiluo driller of chip removal smoothness.
The purpose of this utility model is finished by following technical solution, a kind of machine Zhiluo driller, it includes drill body and the drillstock that links into an integrated entity, described drill body is provided with main cutting edge, front cutting edge and spiral grooves, described spiral grooves is held and is discharged wood chip under boring, and the head of described drill body is provided with the spiral shell point; Described spiral shell pinnacle does not need propulsive force just can rely on the rotary power of electric drill self to advance and retreat automatically on timber, and described drill body is provided with graduation mark.
Described drillstock is positive hexagonal prism, and described drillstock is provided with positioning groove.
Therefore the utility model when high-speed cutting, can keep drilling steady owing to adopted main cutting edge and front cutting edge, adopts the structure of spiral grooves, and the chip removal smoothness has guaranteed that borehole wall is smooth.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: as shown in Figure 1: a kind of machine Zhiluo driller, it includes drill body 1 and the drillstock 2 that links into an integrated entity, described drill body 1 is provided with main cutting edge 3, front cutting edge 4 and spiral grooves 6, described spiral grooves 6 is held and is discharged wood chip under boring, and the head of described drill body 1 is provided with spiral shell point 5; Described spiral shell point 5 withstands on the timber, does not need propulsive force just can rely on the rotary power of electric drill self to advance and retreat automatically, and described drill body 1 is provided with graduation mark 8; Described drillstock 2 is positive hexagonal prism.
Described drillstock 2 is provided with positioning groove 7.
