 -PRODUCT BRIEF-

 PDC is a kind of bit which uses PDC as cutting edge. It is an integrated bit, which has the advantages of high wear resistance, high strength and impact resistance. The bit is one of the three new drilling technologies in the modern world because of its simple structure without movable parts on the body. A large number of applications have proved that diamond composite bit has the advantages of high speed, more footage, long service life, stable operation, less drilling accidents and good borehole quality when it is used in soft medium hard formation. Compared against conventional diamond bit, it has the advantages of low cost and wide range of application. 

PDC drill bit is a kind of new superhard material that is synthesized by carbide alloy and synthetic diamond polycrystal under high temperature and pressure. Compared with the traditional carbide alloy bit, Its service life is 10 to 30 times that of the traditional carbide bit.PDC bit's compound slice cutting structure just makes use of the mechanical property of rock and uses an efficient shearing method to break rock, so as to achieve the purpose of fast drilling.

-APPLICATION RANGE-

Apply to:Water Well Drilling/civil engineering and infrastructure/for rock core drilling/geological coring exploration/Soil Testing and sampling /geophysical survey/mineral exploration and other industries.

Dear User:

Welcome you to choose and use our products correctly!

The geological drill bit produced by our company has a 6-month warranty period.In case of abnormal scrap such as sheet falling, steel body cracking, lamination of composite sheet, etc., the company may make compensation if the situation is confirmed by the quality department of the company.

If it is one of the phenomena listed in the following table, it shall be deemed as normal scrapping, and the company shall not compensate for it:

1,Drop: Wear no more than 10%, send back for replacement, wear no more than 50%, depending on the situation, steel body cracking: wear no more than 30%, send back for replacement; Wear more than 50%, such as artificial improper crack, do not change.

3,Wrong size or thread: New back for new.

4,Weak solder joints, broken wing pieces, etc. : wear not more than 20%, send back for a new; Wear more than 50%, such as artificial improper operation, do not change.

5,The problem of lamination of composite slices: It depends.
