Mincon HDD80PR Pull Reamer

The Mincon HDD80PR pull-reamer hammer uses our proven technology to define the benchmark for HDD tools. Thanks to its patented, reverse-airflow hammer cycle, it can reliably be used to ream pilot bores between 133mm (5¼”) and 235mm (9¼”), to a full hole size of 406mm (16″). Mincon’s design means that minimal feed and rotational force are required from the drilling machine, thanks to the high-pressure, high-volume air that powers the hammer.
