Diaond bits crown shap and applications:


Flat : applicable to drilling different levels of hardness or abrasive formation , generally for single and dual tube drill bits.


Semi-round:good distribution of the diamond at bit face, adapt to a small broken or loose formation ,applicable to drilling medium-hard and hard formation .


Ladder:applicable to drilling medium –hard, broken or iterbedded formations, hole deviation can be prevented .


Serrated: applicable to drilling hard and dense formation , enhancing drilling rate.


Ladder serrated: applicable to medium –hard, have good stability during the drilling .


Gear Type: applicable to harder or dense formations, enhancing drilling rate .


Bottom Jetting : applicable to drilling sedimentary or metamorphic formations which containning more power ,high coring recovery rate and avoid excessive washout of core.
