Frequently Asked Questions

Drill pipes range from Φ42mm to Φ168mm in various specifications, and drilling tools encompass directional drill bits, extrusion reamers, cast flow channel reamers, custom reamers, splitters, protective shorting devices, and various other accessories. We have developed a domestically advanced channel-type automated drill pipe tempering furnace, specifically designed for the characteristics of trenchless drill pipes: small size, varying lengths, high toughness requirements, and small radius of curvature. We possess multiple specialized pipe thickening machines, with a maximum tonnage of 1000 tons, ensuring a smooth transition between the inner and outer thickened areas of integral drill pipes and API large drill pipes. We have multiple friction welding machines, with a 150-ton continuous drive friction welding machine as the core, capable of welding large drill pipes according to API standards. We also possess various general-purpose machining equipment, possessing strong production capacity to guarantee the quality of drill pipe threads and drilling tools of various specifications. With the help of these advanced equipment, and in conjunction with a physical and chemical laboratory composed entirely of imported testing instruments, we are confident and capable of producing trenchless drill pipes and drilling tools that will satisfy you.

We are a professional drilling tools manufacturer with more than 25 years of manufacturing experience since 1998.

We operate our own manufacturing facilities and specialize in producing HDD drill rods, mining drill pipes and drilling tools, water well drill pipes and API drill pipes.

As a direct manufacturer, we provide reliable product quality, competitive pricing and flexible solutions for global distributors, dealers and end users.

We manufacture a wide range of drilling tools for different applications, including:

  • HDD Drill Rods and Trenchless Drilling Tools
  • Rotary Drill Pipes for surface mining

Drilling Applications & Tool Selection Guide

North Star supports drilling applications across HDD trenchless work, mining and construction, and water well drilling. Start with the drilling method, then define the rig, drill string and tooling required for the project. Forged and welded drill pipe, rotary pipe, DTH rods, reverse circulation pipe and supporting tools serve different drilling applications; the product name alone does not establish compatibility.

Compare 3 Core Drilling Applications

Drilling applications, related tooling and enquiry requirements
Application Related products Information to confirm
HDD drilling applications — trenchless utilities Forged or welded HDD drill pipe; drill heads, housings, reamers and swivels. Rig model, pipe dimensions, thread details, bore profile, bend-radius requirements and ground conditions.
Mining and construction drilling applications Rotary drill pipe, DTH rods, reverse circulation drill pipe, adaptors, bushings and stabilisers. Drilling method, rig model, pipe length, outside diameter and connections. RC enquiries also require inner-tube and sealing-interface details.
Water well drilling applications API water well drill rods, adaptors and supporting components. Pipe dimensions, box and pin threads, mating parts, required length and operating requirements.

How should I choose products for drilling applications?

Identify the drilling method first. Compare the product range and specification and compatibility tables, then confirm the selected configuration against the equipment and project requirements. Similar dimensions do not, by themselves, confirm that threads or interfaces match.

What should I send with an application enquiry?

Provide the drilling application, rig make and model, ground conditions, dimensions, connections, quantity and delivery destination. Include a drawing, part number or existing component reference where available. Contact our team to review the requested configuration. For general background on HDD drilling applications, see directional drilling. Product specifications and project-specific selection still need separate confirmation.
