Solitary cone little bit is a variety of deceleration bit, which is the velocity of cone is more compact than the velocity of drill, primarily disorderly reducing broken rock. It is suitable for outdated properly sidetracking and deepening the slim hole drilling procedure underneath substantial rotary velocity and drilling force. 

1. Its application area is wide, not only appropriate for facet drilling, and can be utilised in deep well. 

two. Perform torque is reduced than PDC little bit in the exact same drilling force and formation situation. It can decrease the small measurement gap expansion buckling troubles, so that avoid down hole incidents. 

three. Solitary cone little bit has rewards of the two three cone bit and PDC bit, and make up the down sides of both. It is more appropriate for large plastic development than a few cone bit, also can be applied to tough interlayer which PDC little bit can not deal with other intricate development. 

four. It can realize substantial velocity and special drilling with down hole motor.


core barrel are used for drilling in cohesive and non-cohesive soil beneath groundwater stage. Digga’s drilling buckets are suitable for breaking and ripping tough soil up to medium tough rock.

IADC Specification

First Digit(one~eight):
 -one,two, and 3 designate Metal TOOTH BITS with 1 for delicate,two for medium and 3 for tough formations.
-four,five,six,7 and 8 designate TUNGSTEN CARBIDE INSERT BITS for different formation hardness with 4 getting the softest and eight the toughest.
Second Digit(one~4):
 -1,two,3, and 4 are more breakdown of formation with 1 becoming the softest and four the toughest .
Third Digit(1~7):
This digit will classify the bit in accordance to bearing/seal type-see info on various bearing varieties-and specific guage wear safety as follows:
 -1. CZPT open up bearing roller little bit.
-two. CZPT open up bearing roller little bit,air-cooled.
-3. CZPT open up bearing roller bit with gauge protection which is outlined as carbide inserts in the heel of the cone.
-four. Sealed roller bearing little bit.
-5. Sealed roller bearing bit with gauge security on heel  of cones.
-six. Journal sealed bearing little bit.
-7. Journal sealed bearing little bit with gauge safety on heel of cones.

one. How to get an precise quotation?

Response: You should send out us comprehensive details as below:
-Tricone bits(Diameter, IADC code)

-PDC bits(Matrix or Metal body, blades amount, cutter dimension, and many others)

-Hole opener(Diameter, size of pilot hole, hardness of rocks, thread connection of your drill pipe, etc.)

-Roller cutters(Diameter of cones, model quantity, and so on.)

-Main barrel(Diameter, quantity of cutters, connection, and many others.)

A simple way is sending us photos .


Aside from above, if achievable you should provide a lot more info as under:

Drilling depth in vertical nicely drilling, Drilling duration in HDD, hardness of rocks, Potential of drill rigs, application(oil/gas properly drilling, or water properly drilling, or HDD, or basis).


Incoterm: FOB or CIF or CFR, by aircraft or ship, port of spot/discharge.


The more data provided, the far more specific quotation will be offered.


2. What is the high quality manage for your items?

Reply: All of our creation are in traces of API policies and CZPT:2015 strictly, from signing agreement , to uncooked materials, to each generation processes, to solution complete, to after-sale provider, each and every procedures and sections are in accordant with standard.


three. About guide time,payment conditions, delivery ?
