Product Description

High-Pressure Mining DTH (Down-The-Hole) Drill Bit
Constructed with premium carbide inserts and reinforced alloy steel body, it delivers exceptional penetration rates in hard rock formations like granite, quartzite, and abrasive ore deposits.  The optimized venturi channel design ensures efficient cuttings removal even under extreme downhole pressure, while its symmetrical button layout maximizes impact energy transfer for superior drilling efficiency.  With heat-treated steel matrix and tungsten carbide grade customization options, it resists wear, reduces premature failure, and extends service life in high-vibration mining environments.  Ideal for large-diameter deep hole drilling in open-pit mines, quarries, and tunneling operations.
The use of a wide range:the bit is suitable for carbonate rock, limestone, chalk, clay rock,siltstone, sandstone and other soft and hard.
Each bit is has been precision machined to produce a perfect body, heat treated to the required hardness, given surface compression for fatigue resistance. These are deigned for specific applications for all rock types,hardness's and condition.
