Tapered tools, 11° taper

Rock drilling tools include: drill bit,drill rod, shank and coupling. The piston of drill rig directly impacts the shank, makes impact power reach the bit through rod by the form of stress wave, so as to work on the breakage of rock. The primary breaking way is impacting while the secondary is cutting; both are with high drilling efficiency. Usually the land surface of the earth is covered with loose, unconsolidated material such as soil, clay, silt, sand, gravel and boulders, which varies in depth from a few centimeters to hundreds of meters.Use concentric system can drill this complex formation very well.The systems are available through the whole product range the smallest being for 114 mm (4 1/2″) casing and  largest size available at the moment is for 1220 mm (48″) casing.

Male / Male rod, 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.
For Extension Rod and M/F steel process, the below two different types of heat treatment are used tostrengthen high speed and powerful percussive drill string components to maximize their performance and reliability.
