The MR range of RC hammers is designed to perform at the top end of the performance scale compared to other tools on the market. With extensive testing over the past 18 months the MR range of tools offers some very significant benefits over the MX range of RC hammers.
REVERSE CIRCULATION DRILLING
Performance improvements show up to 20% increase in production in both grade control and exploration applications vs the Mincon MX range. As with all Mincon hammers the tools performed extremely well in deep hole drilling in dry applications and where there is a lot of water in the bore hole. With a variable length available on the chuck sleeve the hammer can be easily set up for either dry or wet hole drilling. Set to become the standard by which RC hammers will be measured, the Mincon MR range of tools get the job done.
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 offer superior wear resistance vs. our competition
Variable sample tube bore sizes for the MR120 and MR132 allows the contractor greater flexibility in setting up his tool
Metal sprayed chuck sleeve and wear sleeve options for greater wear resistance on outside circulation
Ease of service with no special assembly or disassembly tools required

Mincon personnel have a wealth of knowledge and experience in reverse circulation hammer design and manufacture. Mincon has been involved since the acceptance of reverse circulation drilling as an advancement over cross-over sub systems and an alternative the more expensive diamond coring. Bringing this experience to the MX line of hammers produced a design that is second to none in performance, reliability and sample quality.
