Hole-RC01


Our reverse circulation hammers are specifically designed for all kinds of exploration drilling (deep hole and in-pit grade control applications). Whether you are exploring potential sites or working an existing mine, the China KING-LONG RC hammer will guarantee high performance, exceptional reliability and dependable support


Hole-RC02


KING-LONG RC hammers

are essentially the same as conventional DTH hammers, but with an inner-tube that runs through the centre of the entire hammer.


• The cuttings are collected in the holes in the front of the bit and confined and transported in the inner-tube.
• The flushing is in-between the splines of the bit and the chuck.
• The inner-tube is a wearing component and is replaced easily through the top of the hammer.
• In all RC hammers the inner-tube assembly can be removed without removing the backhead.
