MRXT RC Hammer Range
Your drill site doesn’t stand still, and neither does innovation at Mincon. The next-generation Mincon MRXT reverse circulation (RC) hammers use our latest technologies to make exploration drilling even more efficient. Each of these features has been designed and field-tested to ensure that they help deliver high-quality sample and maximum reliability

Efficiency through innovation:
The MRXT series boasts an upgraded check valve and an optional bleed chuck sleeve feature. When equipped, the bleed chuck sleeve and bleed chuck help maintain positive air pressure at the bit face by holding the outside water head above the chuck sleeve

Complete RC Solutions
Mincon has been designing and manufacturing class-leading reverse-circulation (RC) hammers for three decades. We pride ourselves on producing the highest quality, most innovative RC hammers that help drillers achieve high performance and low running costs without sacrificing consistency in sample quality.
The standout feature of the new MRXT range is our top-loading design, which allows for easier inspection and maintenance of the sample tubes. This not only saves time, but also avoids the need for disassembly of the entire hammer As a result, the top-loading design enables faster, safer checking and swapping of sample tubes, ensuring efficient and safe drilling practices while reducing downtime and costs.
