Acedrills' drifting and extension drill rods are for in drifting, tunneling, long-hole drilling, bench and production drilling industries. These rods are produced with round or hexagonal sections in all common thread designs, and in Male/Male (M/M) or Male/Female (M/F) connections. All our drifting and extension drill rods are heat-treated with carburization or high frequency, combinated with phosphorization.

The round cross sections are more prevalent for extension drilling applications. A round rod has less material and thus is lighter to handle and less expensive than an equivalent size hexagonal rod. While hexagonal rod is particularly advantageous for drifting and tunneling drilling. The increased rigidity of hexagonal drill rods enables them to abating hole-deviation and enhances flushing for cleaning holes. Even with the larger cross section, hexagonal steel can still accommodate the same diameter bit as that of an equivalent round steel.
M/F rods provides tighter connections and is easier for handling and quicker for uncoupling than M/M rods, and are potential to drill straighter holes.
Carburization technique is mainly used in the production of big diameter rods to ensure excellent performance. Carburizing is for hardening entire rod to provide an external over entire rod surface area. Carburized steels are used primarily in underground applications and where water is used as a flushing medium. High Frequency technique is primarily used in the production of small diameter rods to reduce fragileness of drill steels. High Frequency is for hardening only the thread ends of the rod. This provides the longevity of the product as well as being more suitable for more drilling condition need. Steels produced with this technics primarily used in surface drilling applications where air is the primary flushing medium. Phosphorising is to improve anti-erosion capability of the entire external rod surface area.
