78mm 4-Blade Non-Core PDC Bit with Cross Design
Specially designed for marble and granite quarrying as well as mine horizontal drilling conditions, our factory manufactures high-performance
78mm 4-blade non-core PDC bits
. Different from traditional spiral body drill bits, this bit adopts an innovative
cross integral structure
, which is a professional efficient drilling tool for horizontal rig stone cutting, transverse piercing and mine roadway horizontal drilling. It perfectly solves the common industry problems of slag blockage, uneven water output and slow penetration in hard stone horizontal drilling.
The symmetric cross blade design ensures uniform force distribution and high drilling concentricity, effectively avoiding drilling deviation and shaking during operation, making it suitable for hard granite and dense marble formations. Equipped with
balanced water outlet channels
, the bit realizes all-round uniform cooling for the working surface, quickly dissipates drilling high temperature, reduces high-temperature wear and tooth burning of PDC cutters, and greatly prolongs the service life of the drill bit. The widened slag discharge groove matched with the cross structure ensures unobstructed debris removal, completely solves jamming and hole blocking caused by stone residue accumulation in horizontal drilling, and maintains stable and fast penetration speed.
This 78mm stone-specific PDC bit supports
custom internal and external threads
, perfectly matching standard 73mm drill rods and compatible with most domestic and imported horizontal drilling rigs. As a professional mine drill bit manufacturer, we provide direct sales and customized processing services. We deliver reliable, cost-effective horizontal drilling solutions for stone quarry cutting, open-pit stone mining and mine roadway drilling projects worldwide.
