RC HAMMER & BITS
The Reverse Circulation (RC) Drill Hammers are of, 4 ½’’- 5” bore. Hammer drill designed to use independent rotation and drill in rock with 4 ½’’ to 8” for various formations under favourable conditions.
The RC Hammers are designed for use for drilling exploratory wells in quarries, open pit mines, coal pit mines, coal where faster exploration is required.
The RC Hammers can be operated on high pressure air. Its drill cycle is designed to make this drill extremely effective. At high pressures like 350 PSI and above, the RCD performs well in applications where high water yields/back pressure is encountered.
