TCI Tricone bits is an ideal solution for both medium formations consist mainly of calcites, dolomites, hard limestones etc and hard formations consist mainly of hard shale, mudstones, cherty limestones etc. Additionally TCI Tricone Bits are much more capable at absorbing the significant amount of heat generated without damaging the drill bit.
Steel teeth or carbide inserts come in a variety of shapes, sizes, and grades of tungsten carbides to address specific drilling conditions. TCI bits offer increased durability over steel tooth bits but also carry a higher cost.

Drilling is a drilling method that relies on the energy of the drill and the drill to act on the roller bit to break the rock. The energy acting on the roller bit by the drill includes the swivel action and the downward thrust. The lower thrust is achieved by the gravity of the drill on the roller bit and the hydraulic cylinder, wire rope or chain on the drill.
Table 1 for the daily tri-cone bit load, for large-diameter roller cone drill bits generally use the upper part or bit weight.
Under the caliber with a Drill Collar, with a large bucket, and add stabilizer (or righting circle).
Large-diameter cone drill bit drilling as much as possible using gas lift reverse circulation drilling, bit life and drill speed will be greatly enhanced

Oil well tricone bits Package and shipping
Package Type:wooden case ,also be packaged according to customers requirement
Transportation:by sea,by air or land transportation.Less than 50kg shipping by courier better
Delivery:If we have stock, the delivery time will need about 2~3 working days. In general, common size tricone bits and PDC Bit,we have stock
If we have no stock,such as the tci reamer and PDC Hole Opener,it will be 7-10 working days in total
How about our Customers feedback ?
The drilling deepth more than 460meters 1 pc Metal seal bearing TCI Tricone Bit
TCI Tricone bit Drilling 3500 meters well no problem
1 pc Hole opener drilling more than 10 well no problem
Drilling to 1600 meter the PDC Drill Bit continue work good enough
