AQ BQ NQ HQ PQ Impregnated core drill bit diamond widely used in wire-line drilling series

Impregnated diamond bits have the widest range of application. They are the most commonly useful bits from medium to super hard formations 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.

Diamond bits Crown Shape

Diamond bits 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 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 interbedded formations, hole deviation can be prevented.
	Serrated	applicable to drilling hard and dense formation, Enhancing drilling rate.
	Ladder serrated	applicable to drilling medium-hard, have good stability during the drilling.
	Gear type	applicable to harder or dense formations, enhancing drilling rate.
	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 .

Toothed bits can get higher drilling efficiency when it is drilling at dense or abrasive stratum with lower drilling speed and pressure. It was especially effective at coal 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.

Application

Geological exploration drilling. 

Specifications of Diamond bits & reamers 

To select the right bit for the job, assess the speed and power of your drill for the size and depths of the holes to be drilled and assess ground conditions such as rock type/formation and down-hole conditions.

Size:
Our bits are available in all standard drilling sizes . Also, non-standard sized bits can be produced according to requirements from clients.

Crown Height:
Our offers crown impreg depths of 9mm, 12mm, 16mm and 25mm .The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.

Waterways:
Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.

Threads:
standard threads as well as regional thread types required by clients are available.

Compatibility:
Our diamond bits and reaming shells are designed to be compatible with all standard core barrels from other suppliers.
