NQ3 Diamond Bits

Impregnated Diamond Core Bits are manufactured with very small, high quality sythetic diamonds, mixed evenly through a metal alloy matrix. 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. In most geological formations, impregnated bits are more economical to use than other bits.


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.

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

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

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


ROSCHEN impregnated bits matrices can be selected by our engineer according to ground conditions at client's work site.


standard Q threads as well as thread types required by clients are available.
