Diamond Impregnated Core Bits

The term “set diameter” refers to the dimension measured on the outside or inside diameter of the matrix body on a core bit on which diamonds, tungsten-carbide elements and/or thermally stable polycrystalline (TSP) elements have been physically set in order to preserve this critical dimension during drilling.

Bit sizes that are not listed in our technical literature or bits with non-standard set diameters may be available on request. Note that some types of cutting media may not be available on some sizes of core bits due to the physical dimensional limitations of the bit crown.


“325 meters with our bits very good in medium hard rock. Thank you!”

– Ontario, Canada

“The successful trial results of the bit prove this bit to be a serious alternative to our current bit of choice at our mine.”

– Australia

“I have a result from a new client in northern Ontario. Their last bits went 60 or 80 meters and with Dimatec bits 212 meter! Good production thank you.”

– North America

“We received the bits yesterday! We are quite pleased with all aspects of this order including the 4-day lead time. Thank you for the expedited service!”

“The meters drilled were above ‘the norm’ and we were well within and even under budget lets say…”

– Canada

“We had a good wear on the crown, the meters achieved are also worth commenting on being consistently all right around the 300’ mark. We’re happy and the reaming shells are also performing well.”

– North America
