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

The company covers an area of 30 acres and a factory building of 15,000 square meters.
Specializing in the production and sales of drilling tools such as Tricone bit, PDC drill bits, Hole opener, roller cone drills, hammer and hammer bit, drill pipes, drill collars, etc. A professional design, production, inspection and foreign trade sales team has been established.
Products are sold to the United States, Canada, Russia, Kazakhstan, Iran, Qatar, Sweden, Germany, Australia, Singapore, Mexico, Colombia and other more than 30 countries. The sales volume reached 15,000 pieces of the roller cone, and the three-cone drill bit 5000 achieved first-class design, first-class manufacturing, first-class product cost performance, and first-class after-sales to achieve win-win for the industry, customers and the company.
Professional team at your service ,2 doctoral professional R&D new technologies, 3 master students’ drawing design, 5 undergraduate graduations. The company inspected the finished semi-finished products, 8 production masters with more than 10 years of experience and several production workers, 6 after-sales service personnel to provide professional technical answers 24 hours a day, 5 website operations and foreign trade personnel to communicate with customers in a timely and efficient manner .
Welcome to visit my factory and inspect the bit quality
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.
