Drill collar is mainly used to provide bit weight to drill bit so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. MS brand drill collar are manufactured strictly from API Spec7-1 and SY5411 standard.
The wall thickness of heavy weight drill pipe is between drill pipe and drill collar. Its structure is similar with drill pipe. It is made from premium alloyed steel. Its both tool joints and middle upset are welded hardbands. Technical parameters meet with API Spec7-1 standard.

Summary Advantages: Needless to replace the internals of the engine head, just handle the handle to operate it. Easy to operate. More time-saving and effortless. Drilling faster and more efficient. Have reached the tip-top level of the same field now, and allow to be replaced with the same kind of the domestic products. Applications: Available for drilling, splitting breaking, ramming, shoveling. And widely used in mining, road contruction, quarrying and national defense construction, etc. Wooden crate
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.
