Medium To Hard Formation Impregnated Diamond Core Drill Bit bq nq hq pq
1. Impregnated diamond core bit
It’s most popular and commonly in the mineral’s exploration field and geology’s exploration field. Nowdays Our company produce three types(Master Series, Navigator Series, Junior Series) is recognized and recommended by more and more customers.
We preciously selected grades of top grade synthetic diamond are distributed in the depth of impregnated bit’s matrix series.The matrix layer of the crown contains a uniform distribution of these crystal that are embedded in a powdered metal bond, for improving lifespan and rate of penetration. The best record of our bit in south africa, single bit’s life span reach amazing 614.40m
In order to help the customer to select suitable bit and reduce customer’s workload, please follow below three steps to choice your bit.

{2}(1)Appropriate hardness of matrix(For some special or complicated ground,we will need to customize the diamond bits according to the actual
drilling conditions.)
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.
