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 an 18 months period the MR range of tools o­ffers some very signi‑cant bene‑ts over it\'s predecessor, the MX range of RC hammers.<br> 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.
