Durable Drill Bit 65-130 for Efficient Drilling

This ball tooth is specially designed for complex rock types and high-hardness scenarios (such as mixed rock strata containing quartz veins). Its core advantages focus on "precise control of 130mm hole diameter + low disturbance in complex rock walls + coating enhanced durability", making it perfectly suitable for scenarios with strict requirements for hole shape accuracy and durability, such as core drilling in deep mineral exploration and long tunnel excavation. The key design is optimized around "precision and stability" : The shape and arrangement of the ball teeth have been precisely adjusted, causing minimal disturbance to the hole wall during drilling. It can strictly control the consistency of the 130mm specification hole diameter, avoiding the impact on the accuracy of subsequent anchor bolt installation and equipment fixation due to hole wall collapse or hole diameter deviation, directly reducing the secondary hole repair process and improving construction efficiency.
