Detailed Product Description


Ultramatrix Core Drill Bits HQ 24 MM - Stage™ 2 UMX Bit for granite





UMX diamond bits have revolutionized mineral exploration. UMX bits drill faster, last longer, and perform in a wider range of drilling conditions and formations. The extended range and versatility of the UMX diamond bits means less tripping out rods and more core in the box.


The UMX diamond bits feature Roschen’s patented Ultramatrix.

Ultramatrix technology enables the use of large synthetic diamonds with an innovative formula, increasing penetration through various ground formations while providing longer bit life.



SSUMX is the original Ultramatrix bit. We  developed an impregnated bit; with large synthetic diamonds, that exceeds the performance and reliability of traditional surface-set diamond bits. Many drillers around the world have reported up to a 200% increase in life over their traditional surface set bits, and profess that the SSUMX is now their only choice for surface-set drilling.



10UMX is free cutting. Our latest addition to the UMX family of bits is a high performance diamond bit with the freest cutting matrix made. It will quickly penetrate the very hardest rock formations.




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.




1)  certifacation Iso 9001:2008

2)  with very small high quality synthetic diamonds mixed.

3)  impregnated   core  bits are more economical to use than other bits.  

4)  can drill a broad range of geological formations from the softest to the hardest rock

5)  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
