Products Description
LEANOMS
Carbide DTH Hammer Button Bits are specialized drilling tools used in Down-The-Hole (DTH) hammer drilling operations. These bits are designed to be attached to the end of a DTH hammer, serving as the primary contact point for rock-breaking and drilling.
Carbide DTH Hammer Button Bits are constructed using high-quality tungsten carbide inserts. Tungsten carbide is renowned for its exceptional hardness, durability, and resistance to wear, making it an ideal material for demanding drilling applications.
The face of a Carbide DTH Hammer Button Bit is equipped with multiple small, spherical or ballistic-shaped buttons. These buttons, also made of tungsten carbide, are strategically positioned on the bit's face to ensure efficient rock-breaking and the swift removal of chips during the drilling process.

product advantages
LEANOMS
Increased Drilling Speed:
Achieves drilling speeds up to 30% faster compared to conventional button bits.
Example: Carbide DTH Hammer Button Bits achieve an average drilling speed of 2 meters per minute, while standard button bits achieve 1.5 meters per minute.
Enhanced Durability:
Extends bit lifespan by up to 50% compared to standard button bits.
Example: Carbide DTH Hammer Button Bits last approximately 500 drilling meters, while standard button bits last around 300 drilling meters.
Optimal Rock Breaking:
Efficient rock breaking and improved chip evacuation result in smoother drilling operations and reduced energy consumption.
Example: Carbide DTH Hammer Button Bits require 20% less energy compared to standard button bits to break the same volume of rock.
Versatility in Rock Formations:
Suitable for drilling in various rock formations, including abrasive and hard formations.
Example: Carbide DTH Hammer Button Bits perform exceptionally well in granite, basalt, and limestone formations.
Higher Penetration Rates:
Faster penetration rates compared to standard button bits.
Example: Carbide DTH Hammer Button Bits achieve an average penetration rate of 1 meter per minute, while standard button bits achieve 0.8 meters per minute.
Improved Hole Straightness:
Minimizes hole deviation during drilling operations.
Example: Carbide DTH Hammer Button Bits maintain a maximum deviation of 1% in hole straightness, while standard button bits have a maximum deviation of 2%.
Reduced Downtime:
Fewer bit changes result in reduced downtime for bit replacement.
Example: Carbide DTH Hammer Button Bits require bit changes every 500 drilling meters, while standard button bits require changes every 300 drilling meters.
Cost-effectiveness:
Long-term cost savings due to extended lifespan, improved efficiency, and lower maintenance requirements.
Example: Carbide DTH Hammer Button Bits provide a 20% reduction in overall drilling costs compared to standard button bits.

LEANOMS
When faced with different rock formations, Carbide DTH Hammer Button Bits exhibit varying performance characteristics. Here's an overview of how they perform differently on different types of rocks:
Granite:
Carbide DTH Hammer Button Bits excel in drilling granite formations. With their high drilling efficiency and exceptional penetration rates, they can quickly advance through the hard and abrasive granite. The hardness and toughness of the carbide inserts enable them to withstand the demanding conditions, resulting in extended bit life and reduced wear.
Basalt:
Basalt formations require effective rock-breaking capabilities, and Carbide DTH Hammer Button Bits deliver just that. The strong carbide buttons on the bit face efficiently fracture the basalt, while the design ensures optimal chip evacuation. This combination enables smooth drilling operations and allows for efficient progress in basalt formations.
Limestone:
Carbide DTH Hammer Button Bits demonstrate excellent performance in limestone formations. They efficiently transfer energy to the rock, resulting in high drilling productivity. The abrasion resistance of the carbide inserts minimizes bit wear, allowing for prolonged drilling without compromising performance.
Sandstone:
When drilling through sandstone formations, Carbide DTH Hammer Button Bits offer a balance between drilling speed and durability. They can effectively penetrate sandstone while maintaining their integrity for extended periods. The precise positioning of the carbide buttons ensures efficient rock fragmentation and chip evacuation.
Shale:
Shale formations pose unique challenges due to their tendency to be more brittle and prone to fracturing. Carbide DTH Hammer Button Bits adapt to these conditions with their optimized chip evacuation and impact resistance. They minimize bit damage and maintain stability during drilling operations in shale formations.
