Halco RC412 Hammer Remet 4"
Halco RC412 Hammer Remet 4" RC Drilling Engineering Projects For Reverse Circulation
Roschen reverse circulation hammer for Mining, quarries, highways and other projects drilling blasting holes, retaining the hole, the mountain reinforcement, anchoring and other engineering holes, geothermal air conditioning holes, wells and other fields.
The RC412 has been designed to give maximum performance in Exploration and Grade Control applications. These hammers have a one piece “integral top-adaptor” which is robust and simple requiring no make-up components, this gives reliability and ease of service. At higher pressures the RC hammers make easy going of even the hardest of rock structures.
RC412 is equipped with a bit catcher to help retrieve shanked bits and collar the hole. The RC4/412 also has a sub adaptor body to suit most dual wall drill pipe.
Suitable for operation at air pressures of 100 - 435 psi (7 - 30 bar).
Drilling diameters of 121 - 136 mm (4 3/4 - 5 3/8").
