As the necessity of coal mining industry, diamond drill bit must be used with drill pipe, but how to match diamond drill bit with drill pipe? Today I will tell you about the collocation of diamond bit and drill pipe and the strength of diamond bit.
What are the conditions of matching diamond bit and drill pipe?
1) Conducive to slag discharge.
2) Drill pipe has little force and is not easy to wear
3) The hole forming effect is better and so on.
Of course, there are a lot of people ask: diamond drill bit strength how to distinguish? Now let's tell you how to distinguish the strength of the diamond bit.
The strength of diamond composite bit is mainly determined by the strength of diamond composite bit. At present, diamond composite bit can be divided into ordinary type, enhanced type and high strength type. Diamond composite bit is mainly divided into 1305 and 1308. 13 refers to the diameter of composite bit (mm). 05(08) refers to the thickness of composite bit (mm).
The normal type is 1305 flat composite sheet, the strengthened type is 1305 spherical composite sheet or 1308 flat composite sheet, and the high-strength type is 1308 spherical composite sheet.
