Drill pipe
The Φ42S spiral geological drill pipe is a high-torque drilling tool designed for mining blasting, coal mine deep-hole drilling, and geological drilling operations. The rod body is made of high-quality alloy steel pipe, and the joint is made of high-quality alloy structural steel. After high-pressure forming and heat treatment, it is connected to the rod body by friction welding, balancing connection strength, bending resistance, and durability.
This model has a rod body diameter of 42 mm, a spiral diameter range of 50-100 mm, a maximum torque of 3000 N·m, a recommended drilling depth of 100 m, and is compatible with drill bit diameters of 65-146 mm. Common lengths such as 1 m, 2 m, and 3 m are available, making it suitable for continuous drilling and cuttings removal under medium-hard geological conditions.

The Φ42S spiral drill pipe can achieve a maximum torque of 3000 N·m, making it suitable for deep-hole drilling in medium-hard formations and helping maintain stable transmission under higher loads.
The rod body uses high-quality alloy steel pipe, and the joint uses alloy structural steel and undergoes high-pressure forming and heat treatment. After friction welding connection, the overall bending strength, fatigue strength, and shear resistance of the drill pipe can be improved.
The spiral rod body helps carry rock cuttings and debris out during drilling, reducing the impact of accumulated cuttings in the hole on drilling efficiency. It is especially suitable for coal mines, mines, and other drilling operations requiring continuous cuttings removal.
Common lengths such as 1 m, 2 m, and 3 m are available, making it easy to combine according to the drilling rig structure, construction space, and target hole depth.
The Φ42S spiral geological drill pipe is mainly suitable for coal mine deep-hole drilling, mining blast holes, geological exploration holes, and other drilling operations in medium-hard formations. Its high torque load capacity and spiral cuttings removal structure help improve continuous drilling efficiency and reduce frequent shutdowns for hole cleaning.
When purchasing the Φ42S spiral drill pipe, it is recommended to confirm the drilling rig model, drill pipe length, target hole depth, drill bit diameter, formation hardness, and connection method. For different drilling rig and drill bit combinations, confirm the interface dimensions and actual matching requirements before placing an order.
Different geological conditions, drilling tool combinations, drilling angles, and operating methods will affect the actual performance, cuttings removal efficiency, and service life of the drill pipe. The final result shall be subject to on-site working conditions and actual technical matching results.
