Rock Drill Rods for Different Drilling Equipment
Different drilling machines require different rod designs and connection systems. Explore common drill rod options for pneumatic rock drills, underground drilling jumbos, and surface top hammer rigs.
01 — Pneumatic Rock Drills
Handheld & Air-Leg Drilling
Handheld and air-leg pneumatic rock drills are commonly used for small-diameter drilling in underground mines, quarries, and construction projects. Tapered drill rods are used with matching tapered bits, while integral drill steels provide a one-piece option for compatible machines.
Common Rod Types:
Tapered Drill Rods | Integral Drill Steels
Equipment Check:
Rock drill model, shank dimensions, rod length, and taper angle (if applicable).
02 — Underground Drilling Jumbos
Underground Face Drilling & Tunneling
Hydraulic drilling jumbos are widely used for face drilling in underground mines and tunnels. Drifter rods are commonly used in these drilling systems to transmit impact energy from the rock drill to the drill bit.
Common Rod Type:
Drifter Rods
Equipment Check:
Rock drill model, shank adapter connection, thread type, rod length, and rod body dimensions.
03 — Surface Top Hammer Drill Rigs
Quarrying, Open-Pit Mining & Bench Drilling
Surface top hammer drill rigs are used for blast-hole and bench drilling in quarries, open-pit mines, and construction projects. Extension rods connect through coupling sleeves, while MF drill rods allow direct rod-to-rod connections.
Common Rod Types:
Extension Drill Rods | MF Drill Rods
Equipment Check:
Drilling system, thread type, rod length, rod diameter, and connection requirements.
Rock Drill Rods Connections & Compatibility
Different rock drilling systems use different connections between drill rods, drill bits, and drilling equipment. Understanding these connections helps ensure proper compatibility and reliable drilling performance.

Checking Rock Drill Rod Compatibility
- Rock Drill & Shank: Confirm the equipment model and required shank dimensions or shank adapter.
- Rod Connections: Check the taper angle or exact thread specifications.
- Drill Bit: Ensure the bit connection matches the drill rod.
- Flushing System: Verify that the flushing passages are compatible with the drilling setup.
How to Select the Right Rock Drill Rods
Choosing the correct rock drill rod requires matching the drilling equipment, rod dimensions, and connection specifications. Check these four key factors before placing an order.
01 — Confirm Your Drilling Equipment
Identify your rock drill or drilling rig model. For tapered and integral drill steels, check the required shank dimensions. For threaded drilling systems, confirm the shank adapter and drill string specifications.
02 — Choose the Rod Length
Select the rod length based on the required hole depth, drilling equipment, and available working space. Check the drill rig’s feed length and whether additional extension rods are needed.
03 — Check the Rod Size & Profile
Confirm whether you need a hexagonal or round drill rod. Check the required steel section, such as H22 or H25, or the rod diameter to ensure compatibility with your drilling system.
04 — Verify the Connection Specifications
Check the exact taper angle or thread specifications at each end of the rod. Ensure compatibility with the drill bit, shank adapter, and coupling sleeves where applicable.
