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.

Drifter rod,T38–Hex 35–R35

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.

Drifter rod,T38–Hex 35–R35

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.
