The drill rod extension is an essential accessory in coal and geological exploration drilling. It serves as a connecting element between the drilling machine and the primary spiral drill rod, ensuring stable and precise torque transmission in deep or hard-to-reach areas.

This product is designed as a smooth rod with a spiral (helical) profile. Each section has a standard length of 1.5 meters and features a hexagonal (hex) connection, providing high stability and secure engagement during operation in challenging mine terrains. It is manufactured from high-strength structural steel, treated for wear resistance and deformation protection under harsh working conditions.

This extension rod is intended for use with spiral drill rods and the AA-1 pneumatic drilling machine, making it ideal for coal seam exploration and geological surveys.
