PQ HQ NQ BQ AQ Wire-line Impregnated Diamond Core Drilling Bit
Impregnated diamond bit have the widest range if application. They are the most commonly useful bits from medium to super hard formation in the mineral exploration industry. THE Hardness and abrasive of the rock formation are the key factors to determine the diamond specifications, concentration and matrix hardness.
Toothed bits can get higher drilling efficiency when it is drilling at dense or abrasive stratum with lower drilling speed and pressure. It want especially effective arc pal formation, using toothed bits can get better water flowing and drilling footage effect. Nowadays, Impregnated diamond bits have been widely used in wire-line drilling series

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.
