43mm Tc Twin Wing Mine Coal Drill Bits
The 43mm Tc Twin Wing Mine Coal Drill Bits from Linqing City Ruilong Drill Co., Ltd. are PDC (polycrystalline diamond compact) bits designed for sandstone and coal mining applications. These bits feature a 2 or 3-wing whole-piece construction with 1-4 water holes, optimised for efficient drilling in medium to super-hard rock formations. The twin-wing design enhances stability and penetration rates in tough geological conditions, while the water holes facilitate cooling and debris removal during operation.
The bits are manufactured using a composite of diamond and hard alloy under high temperature and pressure, combining the hardness of diamond with the impact resistance of tungsten carbide. The carrier is forged from high-grade steel and undergoes fully automatic vacuum heat treatment to enhance mechanical strength. Standard-type bits use Chinese PCD blades, while the super-strong variant incorporates American-made GE blades with 1.5 times the diamond content for superior abrasive resistance. This construction ensures a working life 10-30 times longer than conventional alloy bits, with drilling efficiency improvements of up to 60%.
These PDC bits are deployed across coal mining, oil exploration, geological surveys, and infrastructure projects such as tunnelling and hydroelectric construction. The standard type is suited for rock hardness up to f8, while the strengthened variant handles medium to hard rock up to f12. Buyers should confirm compatibility with their drilling rigs and the specific rock hardness ratings of their sites. The bits are supplied ready for use, eliminating the need for pre-drilling figuration and reducing labour intensity.

Sourcing 43mm Tc Twin Wing Mine Coal Drill Bits from Linqing City Ruilong Drill Co., Ltd. - China Import Guide
Before ordering, verify the exact rock hardness ratings of your drilling site to ensure compatibility with the standard or strengthened PDC bit variants. Confirm the bit’s diameter tolerance and connection type match your rig’s specifications, as mismatches can lead to operational inefficiencies or equipment damage. Request the supplier’s technical drawings or product certificates if available.
Logistics should be coordinated with the supplier to confirm lead times, which may vary based on order volume and production schedules. Clarify Incoterms such as FOB or CIF, as these will determine responsibility for shipping costs, insurance, and risk transfer. Payment terms, including deposits and final payment methods, should also be agreed upon in advance to avoid delays.
Quality checks should include inspecting the bit’s diameter, wing configuration, and water hole count upon receipt. Request documentation such as material test reports for the steel carrier and PCD blades, if applicable. For critical applications, consider third-party inspection or witness testing to validate performance claims, particularly for the super-strong variant with GE blades.
