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.
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.

Kellys are the drive section of the whole drill stem.The manufacturing of the products refers to the standard of SY/T6509-2000 or API SPEC.7-1.AISI4145H alloy steel is used in producing the kellys. Kellys'end, drive cross-section and joint are all processed and tested in terms of API.
Purpose
White Cushion (Amine-Coated Cushion) is a kind of new type drilling cushion for small hole, and is applicable for 0.15mm or less hole on precise multi-layer circuit board. It is designed for substituting bakelite board for meeting the requirements of IS014000.
