Geological PQ,HQ,NQ surface diamond bits/ core drill bits
For Mineral Exploration Industry
Description:
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.
Specifications:
Size: 46~325mm diamond core drill bits with national and international standard

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.
