Water Well Diamond Drilling Bits
1. Advantages of water tricone bits :
(1) Strong resistance to abrasion and impact resistance.
(2) Cutter's quality performance is good
(3) long work life
(4) stocks adequate, time delivery
(5) rich experience in drill bit
(6) good after-sales service
(7) High quality, competitive price
Challenger™ steel tooth cutting structures are engineered to provide the lowest possible drilling costs. Each design has the row placement, tooth spacing and cutter geometry determined to provide high drilling efficiency, minimize tooth wear and prevent tracking in a wide variety of formations and conditions
Extensive shirttail contouring and clearance from the wall of the hole ensures that fine cuttings are carried away from the seal area, providing longer seal life.
Challenger steel tooth bits feature superior gage protection. Semi-round top inserts are strategically placed between gage teeth, and work in unison with full tooth gage hardfacing to provide additional gage and seal protection.
The tooth surfaces are fortified with premium, high-density tungsten carbide hardfacing applied by oxy-acetylen welding for superior wear resistance.
Diamond Enhanced Back Row (D feature)*
One third of the carbide, back-row inserts are replaced with polycrystalline diamond (PCD)-capped inserts to increase gage holding in abrasive applications.
Center Jet Nozzle (J feature)**
A fourth interchangeable jet is installed in the center of the bit to reduce bit balling or provide extra flow capacity. (Available in 8 3/8” and larger bits only)
Challenger bits feature an innovative, stepped shale burn insert. This stepped design is more effective in diverting cuttings away from the seal, prolonging seal life
