In drilling, there’s a lot riding on the smallest part of the drill string. Choosing the right core bit for your conditions can mean the difference between reaching your shift target or lost productivity.
CoreMatrix™ diamond-impregnated bits from Di‑Corp have been re-engineered for enhanced bit life and faster penetration rates across every ground condition to get you downhole faster and stay there longer.
With 21 matrices to choose from and a comprehensive matrix selection chart to guide you, it is easier than ever to find the perfect CoreMatrix bit for your drilling conditions. Bit numbers are clearly identified according to the Mohs Hardness Scale, with three waterway configurations and several specialty options for Abrasive conditions, Extended life, and Free-cutting matrices.
These diamond impregnated coring bits are designed and built in Canada by technical experts with decades of experience. Di-Corp’s Drillers Edge team, led by many years of metallurgic expertise, engineered each matrix to optimize performance and meet the demands of today’s driller.
Drilling is tough work. Get rugged to the core with CoreMatrix bits by Di‑Corp Drillers Edge.
CoreMatrix™ Diamond Impregnated Bits
Drillers Edge works in partnership with you to select or develop an impregnated diamond core bit that works with all your drilling requirements. Our team of experts has an in-depth understanding of the entire product line and how to maximize the performance and life of each bit.
Each unique matrix is designed to cover a wide range of ground conditions, including:
- Soft to ultra-hard formations (Mohs Hardness Scale – 1 to 10).
- Abrasive or non-abrasive conditions.
- Competent, fractured, or broken formations.
Each matrix is made up of premium components (diamonds, powders, and alloys) to achieve maximum performance and withstand the demands of modern drilling ― including high penetration, load, and torque.
All matrices are designed to target a specific rock formation. The CoreMatrix line is engineered to perform in different drilling conditions, depending on rock hardness, rock abrasiveness, required bit life, and penetration rate.
A few of the matrix selections we have available include:
- General-purpose matrices ― perfect starting matrix with an ideal balance between penetration rate and bit life.
- “A” matrices for abrasive formations ― ideal for abrasive rock formations.
- “E” matrices for extended bit life ― an ideal solution when extended bit life is required.
- “F” matrices for free-cutting matrices ― an ideal solution for drilling at high penetration rates.

The crown profiles are designed to fit different drilling conditions: type of rock formation (hardness, abrasiveness, composition), required penetration rate and bit life, and drill rig configuration. Selection of proper crown profile is critical not only to maximizing bit performance but also to ensure no damage occurs down the hole.
CoreMatrix crown profiles are standardized on three waterway configurations.
STANDARD Waterway
- General purpose design for competent, broken, abrasive, and non-abrasive formations.
- Allows for maximum matrix volume and face contact area.
- Requires mid to high-power drill rigs to operate.
- Delivers maximum bit life.
PIE SHAPED Waterway
- Superior flushing capability
- Suitable for mixed formations containing broken and competent zones.
- More difficult conditions that require increased fluid flow (coarse-grained, fractured, and broken).
- Requires mid-power drill rigs to operate.
- Perfect balance between penetration rate and bit life.
TURBO Waterway
- High productivity ― reduced contact area allows for increased penetration rates.
- High performance (free cutting) under low weight on the bit.
- Suitable for competent formations
- Requires low to mid-power drill rigs to operate.
- Delivers maximum penetration rate.
For more difficult conditions, crown profiles are offered with additional configurations to meet special drilling requirements.
Crown Height
Our bits are manufactured with crown heights of 10mm, 13mm, 16mm, 20mm, and 26mm.
Wide ID Opening
- For STANDARD and PIE SHAPED Waterway.
- More difficult conditions that require increased fluid flow (coarse-grained, fractured, and broken).
- Reduced contact area allows for increased penetration rates.
SUPERFLUSH (Deep ID) Opening
- For STANDARD, PIE SHAPED, and TURBO Waterway.
- Conditions with unconsolidated/broken formations.
- Lost circulation conditions where heavier muds are required.
- Designed for improved water flow with minimized flushing of core sample.
BIT FACE DISCHARGE
- For STANDARD, PIE SHAPED, and TURBO Waterway.
- Difficult conditions where the core sample is susceptible to washing.
