MX5456 RC Hammer (4 1/2" Metzke) Mincon Reverse Circulation hammer
Roschen can manufacture MX5456 series RC Hammer, which have good drill in gold, mining site.
The Mincon Xploration (MX) 5456 is a high performance geological sampling tool that provides trouble free operation in all kinds of demanding conditions manufactured by Roschen. It delivers superior penetration rates versus other manufacturers with extremely smooth drilling and continuous sampling. Like all Roschen DTH hammers, the MX maintains excellent operating pressure over an extended service life and overall is the tool you require to get the maximum out of all your equipment. Roschen Products are all manufactured in house, and all processes are controlled by Roschen's experienced Engineering Department. This guarantees that the quality you “Expect” is always delivered.
Key Features and Benefits
. Patented mounting system for fixed internal components.
. An extremely sturdy shank with a short length allows for greater transfer of energy between the piston and bit.
. Variable chuck sleeve lengths for varying drilling conditions.
. Single piece sample tube assembly.
. Specially heat treated sample tubes over superior wear resistance vs. our competitors.
. Variable sample tube bore sizes allows the contractor greater flexibility in setting up his tool.
. Hardened wear sleeve for optimum wear resistance even in the most abrasive conditions.
. Multi-start threads on backhead and chuck ensure easy coupling/uncoupling of hammer.
. Metal sprayed chuck sleeve and wear sleeve options for greater wear resistance on outside circulation.
. All critical internal components are heat treated under strict control to maximize tool longevity.
. Ease of service with no special assembly or disassembly tools required.

Air Pressures are given for compressors operating at seal level at 20° C (68º F). Corrections to actual compressor volume should be made to account for temperature, altitude and relative humidity.
DTH hammers must receive a constant supply of proper rock drill oil to protect the internal components and to provide a good air seal between the hammer's running surfaces for efficient drilling. Roschen recommends the use of Roschen Losonsafe® Rock Drill Oil (RDO) to maintain optimal performance and extend the life of the internal components. The correct consumption of oil is dependent upon the air volume and conditions. Please refer to the lubrication graph below for recommendations. When drilling in wet conditions the normal amount should be doubled. There should be visual evidence of oil around the drill bit shank and within the tube joints when changing tubes.
If using petroleum based rock drill oils, the recommended grade of oil is dependent on the ambient temperature and the operating pressure. As a rule of thumb, ISO320 grade rock drill oil should be used whenever possible as the hammer is a high frequency tool, however, where the pump cannot pump the oil in colder conditions, a lower grade of oil can be used as per the graph below.
