China Impregnated Diamond Core Bit

1. The impregnated diamond bits are the most commonly used bits in the
mineral exploration industry as they have the widest range of application.
2. Impregnated Diamond Core Bits are manufactured with very small, high
quality sythetic diamonds, mixed evenly through a metal alloy matrix.
3. The matrix erodes away at the same rate as the diamonds become worn
and rounded. Thus new sharp diamonds are exposed to continue cutting
through the rock rock.


1. High wear resistance and impact-resistant toughness
2. Long drilling life
3. High drilling efficiency
4. Labor intensity can be reduced
Hollyland core bits can drill a broad range of geological formations from the softest to the hardest rock, widely used in all kinds of drillings for prospecting, water and electricity building and construction industry of road, railway,
bridge and building taking out core to examine stake,etc.
6mm,8mm,9mm,10mm,12mm,14mm,16mm
