It states connection column bottom and is provided with mounting hole, the connecting pole is cylindrical structure, and the connecting pole top movable is connected with shaft,
And the diameter of the shaft is less than connection column diameter, the shaft can flexible rotating, be installed with drilling tail at the top of the shaft,
The length of the drilling tail is more than connection column length, and the length of the shaft is less than connection column length, and the shaft is with drilling tail
Cylindrical structure, the drilling tail top is fixedly connected with drill body, and the drill body is stepped construction, is fixed at the top of the drill body
Drill bit is installed, and the drill bit can be replaced flexibly, is provided with chip pocket on the outside of the drill body, the chip pocket is provided with centainly
Radian.
Further, hole edge can slightly be machined away a part in 90 degree of part to reach, forms 2 45 degree
Excessive angle, the drill body are stepped construction.
Further, make shaft rotation flexible to reach, reduce axis friction, the diameter of the shaft is less than connecting pole
Diameter.
Further, chamfer drill can be connected on machine to reach, the connection column bottom is provided with mounting hole.
Further, casey when preventing from causing the chamfer drill rotate to reach, improves the chamfer drill service life, the chip pocket is
Symmetrical expression distribution.
Further, efficiency is higher when so that the drill body is drilled in order to reach, speed, and the drill body is conical structure.
Further, in order to reach the chamfer angle that can change chamfer drill, use scope is wider, and the drill bit can be flexible
It replaces.
The beneficial effects of the utility model are：Chamfer drill structure connection is compact, and using simple, chamfer drill is alloy material
It is made, hardness is higher, can improve service life, and drill body is stepped construction, and bore edges are excessively sharp in order to prevent, easily make
It is also relatively difficult when the components such as the injury of pairs of people, mounting screw, axis, it is in 90 degree of part hole edge, slightly machines away
A part forms 2 45 degree of excessive angle, and chip pocket is distributed to be symmetrical, can run chamfer drill safety high speed, connecting pole bottom
Portion is provided with mounting hole, and chamfer drill can be fixedly attached on machine, and shaft is flexibly connected with connecting pole, fixed peace at the top of shaft
Equipped with drilling tail, shaft is made drilling tail can be driven to rotate, so as to drive drill body and bit, safety is higher, stability during work
By force.
