Shandike, a manufacturer of rock drilling tools, produces hexagon-shaped drill steel for rock drill bits.
To enhance strength at the rock drill end and accommodate larger diameter and shank adapters, it is common to increase the drive end of drifting drill steel. Drill steel is available in various standard lengths to match the drill feeds of multiple drifting jumbos. Since the coupling does not enter the hole, a bit diameter closer to the steel diameter can be utilized, which improves flushing and hole accuracy.
Shandike offers drill bits, couplings, shank rods, and tunnel rods in lengths ranging from 2440mm to 6435mm (8′-21′) with R25, R28, and R35 bit end threads and standard shank end thread types. The hexagon body sizes range from H25 to H35, and round rods are available with a diameter of 39mm. Male/Female tunnelling rods are also available in 35mm hexagon and 39mm round.
Hexagon drifting drill rods with a hex size of 35 have several advantages:
The cross-sectional dimension of the material is measured across the flat, providing increased rigidity and weight.
The cross-sections transfer energy more efficiently and reduce annuls in the drill hole, enhancing flushing.
The smaller space combined with the corners of the steel creates turbulence in the hole, keeping heavier cuttings moving, especially in horizontal holes.
The rigidity of the cross-section allows for the use of a larger thread.
Rope threads, such as R32, have a low pitch (12.7mm) and a small angle of profile. They range in size from 22mm to 38mm and have good wear properties but poor uncoupling. They are ideal for single-pass or short-hole drilling applications, such as underground tunneling, that require infrequent uncoupling. Rope threads larger than R32 are not recommended for extension drilling with high-powered drills due to difficulty in uncoupling.
HM or “T” threads, such as T38, have a larger pitch and a larger angle of profile than rope threads. They come in sizes 38mm, 45mm, and 51mm and have excellent wear properties and good coupling qualities. They are ideal for extension drilling with multiple steel, compatible with heavy high-torque rock drills for surface and underground applications.

Reverse Circulation (RC) Drilling Rods: Introduction, Characteristics, Applications, and Comparative Analysis
Reverse Circulation (RC) Drilling Rods, also known as double-wall or double-layer drill rods, offer a unique and efficient drilling solution. Here’s a detailed introduction to their structural characteristics, functions, applications, specifications, selection considerations, and a comparative analysis with normal circulation drilling rods.
Structural Characteristics
RC drill rods feature a double-layer structure comprising an inner pipe and an outer pipe. This design creates an annular gap, which serves as a passage for pumping flushing media (like water or mud) to the hole bottom during drilling operations. The inner and outer pipes are connected using specific methods to ensure effective transmission of torque and pressure. The outer tube typically employs threaded connections, while the inner tube often uses a plug-in design with a sealing device at the connection point.
Functions and Applications
The primary function of RC drill rods is to deliver flushing media to the hole bottom via the annular gap. This media cools the drill bit, carries away drilling debris, and maintains hole wall stability. Simultaneously, the inner tube acts as a return conduit for the flushing media and drill cuttings, transporting them back to the surface. RC drill rods are extensively used in geological and mineral exploration, as well as hydrological well drilling. Their efficient and stable drilling performance makes them indispensable for boreholes with diameters of 84mm and 93mm, reaching depths of up to 300m.
Specifications and Parameters
RC drill rods come with varying specifications and parameters depending on the manufacturer and application. Common specifications include outer tube outer diameters (O.D.) ranging from 88.9mm, 101.7mm, to 114.3mm, inner tube inner diameters (I.D.) varying based on the outer diameter and wall thickness (commonly 38.1mm, 50.8mm, and 63.5mm), standardized wall thicknesses for both inner and outer pipes, and customizable lengths to fit drilling requirements (common lengths include 3m, 4.5m, and 6m).
Selection and Purchase
When choosing and purchasing RC drill rods, consider factors such as drilling requirements (including wellbore diameter, drilling depth, and geological conditions), manufacturer reputation (opt for manufacturers with a solid reputation and extensive experience), and price and cost-effectiveness (ensure quality while considering the price factor).
Comparative Analysis with Normal Circulation Drilling Rods
In summary, Reverse Circulation RC Drilling Rods hold significant application potential and market demand in geological and mineral exploration. When selecting and purchasing, comprehensive consideration of factors like drilling needs, manufacturer reputation, and price is crucial to ensure the drill rods meet actual operational requirements.
