Product Description

Far Eastern Drilling are API (API-7-1 & API Spec Q1) factory specializes in drill bits, such as Diamond Core Bit,Tricone Bit,PDC Bit,Hybrid Bit,HDD Hole Opener,Foundation Roller Cone Bits and related drilling tools,application fields include large-scale open-pit mining, such as open-pit coal mines, iron mines,copper mines and molybdenum mines, also the non-metallic mines.With the increasing in variety of type,it is also widely used in quarrying ,foundation clearing, hydrogeological drilling,coring, tunneling in raillway transportation department and shaft drilling in undergound mines.

 

 

The surface set diamond bit is produced from a single layer of natural diamond setting on the surface of bit crown with hard matrix.
Surface set diamond bit is mainly recommended for drilling soft to hard formations. Generally speaking, surface set diamond bit can provide satisfying penetration rate.
To choose a right surface set for the formations drilled, we need at least consider the following aspects: diamond size, diamond grade, profile design.

Principle of choosing diamond size--the harder the rocks, the smaller the diamond size should be.

Profiles of surface set core bit:
Semi-round: it is mostly used in the core bit with bit kerf thickness less than 11mm. It can drill various formations. The core bit with semi-round profile has long bit life, and can avoid damage; while the bit kerf thickness is over 11mm with semi-round profile can be applied in drilling abrasive  formations.
Stepped profile: core bit kerf thickness over 11mm usually has this kind of profile. Bit with Stepped profile can obtain high penetration rate with good stability in drilling. However, it is not recommended in fractured very abrasive formations. When the core bit of bit kerf less than 11mm has stepped profile can facilitate drilling speed and have better drilling stability.

 

Diamond Size	Formation Drilled
10/20 SPC*	Soft formation
20/30 SPC	soft to medium formation
30/40 SPC	medium formation
40/60 SPC	Medium to hard formation
< 60/80 SPC	Very hard formation
* SPC is short for Stone per Carat** 40/60 is Forsun standard diamond size for natural diamond core bit*** Other sizes are available as per request

Rule of selecting diamond grade--the harder the rocks, the better the diamond grade should be.

 

Diamond Grade	Formation Drilled
A Grade	Soft formation
AA grade	Soft to medium formation
AAA grade	Hard to very hard formation
* AA grade is Forsun standar diamond grade used in natural diamond core bit

 

 

FAQ
1. How to get an exact quotation?
Answer: Please send us detailed information as below:
-Tricone bits(Diameter, IADC code)
-PDC bits(Matrix or Steel body, blades quantity, cutter size, etc)
-Hole opener(Diameter, size of pilot hole, hardness of rocks, thread connection of your drill pipe, etc.)
-Roller cutters(Diameter of cones, model number, etc.)
-Core barrel(Diameter, quantity of cutters, connection, etc.)
A simple way is sending us photos .
Besides above, if possible please provide more information as below:
Drilling depth in vertical well drilling, Drilling length in HDD, hardness of rocks, Capacity of drill rigs, application(oil/gas well drilling, or water well drilling, or HDD, or foundation).
Incoterm: FOB or CIF or CFR, by plane or ship, port of destination/discharge.
The more information provided, the more exact quotation will be offered.
