core drill bits for hard rock
1.balanced force design
2.reasonable layout of PDC cutters
4.high speed
5.adequate stocks
Characteristics of diamond core drill bits for hard rock :
-Arc type crown design and blade type cutter layout result in high ROP, high core recovery reate and long working life of bit, etc.
-Use both PDC cutters and diamonds for gage protection for extended bit life.
-Dynamic flow simulation technology is employed to optimize hydraulic design of the bit and enhance the bit’s cleaning and cooling abilities.
-Inner and outer diamond gage protection. The water course is located at inner gage protection and consequently, cutting elements can receive sufficient cooling and cleaning.
-Force-balance technology is used to improve stability of the bit and prevent the bit from balling up.
Diamond core drill bits for hard rock with matrix or steel body
Our PDC core bits are the most cost effective way to drill or a core sample. Our bits have 9 or 12 PDC cutters standard. The bits can be constructed from matrix body or steel body. The matrix body bit will last longer initially but can crack after substantial use. The steel body bit is can be repaired and retipped at a considerable cost savings compared to purchasing a new bit.
These Diamond Bits use polycrystalline diamond (PDC) cutters to shear rock with a continuous scraping motion
1 Cutting structure is force balanced and bit blade is asymmetrically designed so that the coal on bit is balanced that resulting better stability of the bit.
2 Main cutters are high performance PDC cutters to insure service life of the bit while improving ROP
3 Cutter exposure is optimized to insure the bit can achieve higher ROP is soft to medium formations
4 Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.
5 Hydraulic system of the bit is optimized using dynamic flow palters simulation technology to enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.

WDT 6 blade diamond core drill bits are designed to be the primier drilling bit with the greatest amount of core recovery in soft interbedded with medium formations of 2-5 category of hardness.
These bits are distinguished by an increased core recovery rate as they cut through the formation smoothly & focus a consolidated core sample through the centre of the barrel.
WDT core bits are equiped with stabilizing inserts and cutters of increased abrasive and wear resistance. These core heads are designed to track symmetrically and produce straight non-deviating holes & cores.
29 core bits WDT style matrix or steel body
A - 5.50” X 9 cutter
B - 5.750” X 12 cutter
C - 6.125” X 12 cutter
All sizes and IADC codes of drill bits are available.
Special requirements of different models can be customized.
