Diamond core drilling bit with high penetration rate and longlife span

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.

Our impregnated bits are manufactured to give optimum penetration rates and bit life, which is required to keep the cost of diamond drilling to a minimum.

Superior performance
The bits cutting ability has been developed to allow high penetration rate or low weight on bit when formation demands it.The exceptiona ldurability and superior abrasion resistance have proven to increase drilling performance for a broad range of applications.
