Advantage

Advantage : 1. High temperature heat treatment forged alloy steel .

 

2. Carbide teeth with high strength and toughness work more efficiently

 

3. Tooth palm lip hard welding surface with hard alloy ,Effectively prevent the drill bit wear and tear work

 

4. Head OD protection to effectively reduce head wear in abrasive formation and extend bit work 

  

5.Directional jet enlarges lateral flow area and helpful bottom hole cleaning and increase of ROP

 

6. Lubricating system protection of bearing and seal system of bit extend bit work life

 

7. API REG Connection

 

8.Rubber sealed and metal sealed bearing

Customer visit:

 Welcome to visit  my factory and inspect the bit quality 

 
Packaging & 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.

 

This isJenny, already have 6 years working experience for this section. Already make many friends from different countries. I am very pleasure to help them solve some difficult problems for the HDD drilling reamer and tricone bit, and find the more suitable drilling products. 
We believe double win is what we want.
If you have any questions, welcome to talk with us
