Product Description

Product Description

Cross Bit

Cross Bit is a high-efficiency, wear-resistant and precise positioning rock drilling tool, widely used in mining, tunnel excavation, geotechnical engineering, highway infrastructure and metallurgical high-temperature operations. Its core advantages lie in high rock-breaking efficiency, strong impact resistance and precise positioning. With the cross-shaped cutting edge structural design and high-quality materials, it is suitable for various formations such as medium-hard rock and hard rock, and has become the core equipment for modern rock drilling operations, which can effectively reduce construction costs and improve project progress efficiency.

Efficient Rock Breaking, Precise Positioning: 

Wear-Resistant and Impact-Resistant, Durable: 

Adopting a unique cross-shaped cutting edge structure, the cutting surfaces are evenly distributed, which can achieve precise positioning and not easy to deviate when in contact with rocks. The drilling speed is more than 35% higher than that of traditional blade bits, greatly shortening the single-hole operation time; the cross-blade design disperses the impact force, suitable for drilling in hard rock and medium-hard rock. The "non-grinding service life" can reach 5-6 times the grinding life of blade bits of the same diameter, reducing auxiliary working hours for bit replacement and grinding.

The cross cutting edges are made of high-hardness tungsten carbide-cobalt alloy, fixed by high-temperature sintering and precision inlay technology, with a hardness of above HRC85, which can effectively resist rock friction, impact and wear; the shank is made of 42CrMo high-strength cast steel, strengthened by heat treatment, the impact toughness is increased by 50%, avoiding operation interruption caused by shank breakage and deformation, and suitable for long-term continuous operation in complex formations.
