Alloy Steel Downhole Drilling Tools Down The Hole Hammer Forging Casing

Description:

The DTH hammer is the shortened form of down the hole hammer. And here in Wuxi Drilling Tools Factory Co.,Ltd, we have WC pneumatic DTH hammer and GQ through DTH hammer.

The WC series has no valve structure, and its air consumption is quite low. Moreover, it is capable of working together with various drill rods and drilling rigs.

The impactor of our GQ through DTH hammer features simple structure, superior performance, reliable operation, convenient maintenance and low air consumption. Additionally, this series of down the hole hammer is capable of wireline coring and reverse circulation continuous coring. This series of hammer is widely used for coring and sampling exploration in mineral geology, hydrogeology and engineering geology.

The main components of the down the hole hammer include spline bushing, piston, inner cylinder and core tube.

As for its packaging, we will pack this kind of DTH hammer strictly according to requirements of our customers. For hammers to be exported, standard plywood wooden boxes will be used.
