Abstract
The utility model discloses one arranges tooth to weld diamond thin-wall drill bit, comprise drill body, described drill body comprises Part I, Part II, Part III and Part IV, described Part I, Part II, Part III and Part IV are from top to bottom arranged according to this, the diameter of described Part I is less than the diameter of described Part III, described Part II is connected between described Part I and Part III, the outer surface annular of described Part II is provided with the Cooling Holes of more than four, described Cooling Holes is tilted to lower setting, described Part IV comprises the cutter head of two or more differing heights, be crisscross arranged between the described cutter head of variant height, this device adopts the cutter head of differing heights, and the contact surface between single and cut object is less, improves stock-removing efficiency, simultaneously the cutter head of multiple differing heights, and the cutting ability making this device can remain higher, increases the service life.
Description
Technical field
The utility model relates to a kind of drill bit, particularly relates to one and arranges tooth to weld diamond thin-wall drill bit.
Background technology
Conventional diamond broken wall drill bit is only equipped with a kind of cutter head of height, and in use for some time, cutter head is worn, and impact is normally cut, and after cutter head is worn, needs grinding again just can use, comparatively delays the duration.
The stock-removing efficiency of the cutter head of single height is lower simultaneously, is therefore not suitable for promoting the use of.
Utility model content
The technical problems to be solved in the utility model is to provide one and arranges tooth to weld diamond thin-wall drill bit, this device adopts the cutter head of differing heights, contact surface between single and cut object is less, improve stock-removing efficiency, the cutter head of multiple differing heights simultaneously, the cutting ability making this device can remain higher, increases the service life.
For solving the problem, the utility model adopts following technical scheme:
One arranges tooth to weld diamond thin-wall drill bit, comprise drill body, described drill body comprises Part I, Part II, Part III and Part IV, described Part I, Part II, Part III and Part IV are from top to bottom arranged according to this, the diameter of described Part I is less than the diameter of described Part III, described Part II is connected between described Part I and Part III, the outer surface annular of described Part II is provided with the Cooling Holes of more than four, described Cooling Holes is tilted to lower setting, described Part IV comprises the cutter head of two or more differing heights, be crisscross arranged between the described cutter head of variant height.。
As preferred technical scheme, the close tip position place of described Part I is provided with knurled portions.
As preferred technical scheme, described Part I, Part II and Part III are integral type.
As preferred technical scheme, the inside of described drill body is provided with chip-removal hole, and described Cooling Holes communicates with described chip-removal hole.
The beneficial effects of the utility model are: this device adopts the cutter head of differing heights, contact surface between single and cut object is less, improve stock-removing efficiency, the cutter head of multiple differing heights, makes the cutting ability that this device can remain higher simultaneously, increase the service life, this device is convenient to entering of cooling fluid simultaneously, and avoid the overheated rear wearing and tearing of cutter head, the structure of this device is simple, install and use more for convenience, being applicable to promoting the use of.
