Whole Sale Max 17 Inch Steel Gear Tricone Drill Bit For Drilling Rig
Product Description
The tri-cone drill bit is a versatile tool in the drilling field. It is mainly used in various fields such as drilling, exploration, and petroleum. It is an indispensable guide drill bit in trenchless technology.
According to the cutting material, it is divided into two main types: TCI drill bits and steel tooth drill bits, each of which provides specialized advantages for specific applications. TCI drill bits use high-strength and high-toughness carbide teeth, and the tooth row structure, number of teeth, and tooth exposure height are optimized. Its unique alloy tooth shape can maximize wear resistance and improve cutting efficiency.
Features:
1. Bearing polishing process improves the service life
2. Hardfacing and Tungsten Carbide Inserts for Leg and shirttail protection
3. Heel Inserts and Build up welding on the Steel milled teeth
