Our Reverse Circulation Drilling tools including the RC hammers and RC Button Bits.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, our RC hammers will guarantee high performance, exceptional reliability and dependable support.
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 KingKong RC hammers the inner-tube assembly can be removed without removing the backhead.
