Male/female (m/f) rod, speed rod M/f drill steel is an alternative to couplings sleeves to include the female part of the threaded connection as an integral part of the drill steel. M/f drill steel provides more rigid connections and is easier to uncouple and handle. The service life also tends to be better than with separate couplings. The advantages of drilling with m/f steel include: easy handling, quicker uncoupling, tighter connections, the potential to drill straighter holes, and longer service life.

The UV laser marking machine is developed by using a 355nm UV laser. This machine uses a third-order intracavity frequency doubling technology. Compared with infrared lasers, the 355nm UV laser has a very small spot, and the marking effect is directly interrupted by a short-wavelength laser. The molecular chain greatly reduces the mechanical deformation of the material. Thermal deformation (cold light), because it is mainly used for ultra-fine marking and engraving. It is especially suitable for applications such as marking, micro-hole drilling of food and pharmaceutical packaging materials, high-speed dicing of glass materials, and complex pattern cutting of silicon wafers.
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.

The pneumatic pick is a tool with compressed air as its power. The compressed air is distributing alternatively through the tube-shaped distributing valve into either end of the cylinder, so that the hammer is reciprocating motion in it, which impacts the tail-end of the pick rod and drives the pick rod into the rock or strata of mine, thus causing them to split into pieces.
