Non-Coring Bits

Diamond impregnated non-coring bits are considered to be the first choice for a wide variety of full hole drilling operations. Their availability in a variety of matrix types provides a high degree of flexibility that allows them to perform effectively in formations that range from medium-soft and abrasive to hard and non-abrasive. These bits have the widest range of application in the Dimatec non-coring bit family.

Typically, these bits are used for either directional (steerable) drilling operations or for full hole drilling where a core sample is not required.

Diamond impregnated non-coring bits are available for hole sizes in the range of A-size (Ø 48 mm / 1.875 inch) to P-size (Ø 123 mm / 4.828 inch).

These types of bits are supplied with industry standard thread connections. Other thread connections may be available to suit specific customer needs.

Unless otherwise specified, the bits in this range are supplied with a V-ring face profile. Bit face flushing is achieved through face discharge fluid passages that feed into several large waterway canals.

The gauge diameter setting on these bits is comprised of a combination of thermally stable polycrystalline (TSP) synthetic diamond elements and tungsten-carbide wear pads.


“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
