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.

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.
