Diamond drilling bit Crown Shape 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 ar 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 interbedded formations,hole deviation can be prevented
Applicable to drilling medium -hard,have good stability during the drilling
Bottom jetting : Bottom jetting applicable to drilling sedimentary or metamorphic formations which containing more power,high coring recovery rate and avoid excessive washout of core.
