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.

Power Screw Bits
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.
