1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

Drilling technology has evolved substantially over the past few decades, leading to significant advancements in the tools and materials used in excavation and construction. Among these tools, the 20mm drill rod has emerged as a popular choice due to its exceptional flexibility and efficiency in various applications. This article will explore the characteristics, advantages, and diverse uses of 20mm drill rods across different industries.

Bullet teeth are specialized cutting tools utilized primarily in auger operations for drilling through tough soil, rock, and other challenging materials. Characterized by their streamlined, conical design, these teeth are engineered to penetrate efficiently and minimize the required drilling force. Their unique shape allows for optimal cutting performance while maintaining durability in demanding conditions.
