Sourcing RC Drill Rods in Australia

Manufacturers of RC drill rods

Several companies with operations in Australia publish information indicating direct involvement in the design and manufacture of RC drill rods or dual-wall drill pipes.

• Harlsan Industries offers RC drill rods designed for demanding conditions, with product information highlighting heavy-duty construction, inner-tube sealing and global shipping from Western Australia. RC drill rods form a core part of Harlsan’s RC equipment range alongside subs and other drill-string components.
• Metzke describes a long history in RC technology and supplies RC drill rods and accessories in a range of diameters, threads and lengths. Metzke’s RC systems and rod designs have been widely adopted in Australian reverse-circulation drilling.
• Black Diamond Drilling (BDDrill) supplies Remet-style RC reverse-circulation dual-wall drill pipes in several diameters and lengths, listed as part of its RC drilling tools catalogue. These pipes act as RC drill rods within Remet-based drill strings.
• Corporaal Enterprises produces drill pipe using high-tensile steel and specialised inner-tube sealing technology for RC drill-rod inners, positioning itself as a manufacturer of drill rods and related consumables.

These manufacturers typically publish technical details such as outside diameter, internal diameter, thread type and standard lengths, which contractors review when selecting rod strings or matching new rods to existing fleets.

Suppliers and distributors of RC drill rods

In addition to manufacturers, a number of suppliers stock RC drill rods or help source them for projects within Australia.

• RockSmith lists RC drill rods suited to reverse-circulation projects, with information indicating availability across standard lengths and multiple thread types, including common standards such as Remet, Metzke, RRE, Westrod and others.
• QP Mining Supplies includes drill-rod products and RC drill-rig fittings within its catalogue, and can assist with supplying drill rods and associated hardware from its Perth-based operation.
• RCDrilling.com notes that Harlsan has been supplying RC drill rods and other drilling products to Western Australian drillers for decades, acting as a reference point for operators seeking RC drill strings and related tooling.
• Drilling equipment brokers and wholesalers, such as Drilling Equipment International and similar organisations, list drill pipe and RC drill rods within their used and surplus equipment inventories, which can be relevant for contractors expanding or replacing existing strings.

Stock levels, supported thread types and size ranges can vary between suppliers and over time. It is common practice for drillers to confirm current availability, connection details and any compatibility with existing strings directly with suppliers before placing orders.

Technical considerations when sourcing RC drill rods

Because RC drill rods operate under high loads and are central to sample return, selection is usually based on technical criteria rather than brand alone. Common factors considered by MyDrill users include:

• Required rod diameter and length, including how these interact with rig capability, hole size and expected depths.
• Thread type and connection design (for example Remet, Metzke or other patterns), ensuring compatibility with existing subs, hammers and ancillary equipment.
• Inner-tube sealing approach, material selection and anticipated service life under the ground conditions expected on site.

These issues are typically addressed in direct discussions with manufacturers or suppliers, supported by up-to-date technical data sheets, rod-string drawings and the contractor’s own operational experience.
