Product Description
HA series steel tooth bit:
1) "O" ring sealed journal bearing
Journal bearing structure with head bearing hardfaced and cone bearing silver plated to improve load capacity and anti-galling ability of the bearing. More wear and high-temperature resistant highly saturated Buna-N rubber 'O' ring is used to improve reliability. Larger 'O' ring section reduces pressure on the seal, and the boss at outer end of the seal is also helpful for reliability of the seal.
2) Special gage protection on cone
A row of trimmers is added between heel row and gage row compacts. As a result, not only cone shell is protected, but also the borehole wall is properly trimmed.
3) Head OD reinforcement
Head OD are designed with carbide inserts to protect the shirttail and seal to effectively improve the bit's ability to prevent diameter shrinkage.
4) Hardfacing on shirttail
This feature can provide better protection for seal and bearing to extend the bit's service life.
5) Center nozzle
Center nozzle can avoid bit balling, eliminate fluid stagnant area at bottom hole, increase rising velocity of drilling cuttings, and improve ROP, which is suitable for drilling formations from soft to middle soft with low compressive strength and high drillability.
