What is the working principle of diamond core bits? The drill bit that makes the cutting edge is called a diamond core bit. The drill bit is an integrated drill bit. The entire drill bit has no moving parts. The structure is relatively simple, with high strength, high wear resistance and impact resi
What kinds of drill pipe can be divided into? The drill pipe is a steel pipe with thread on the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device located at the bottom end of the drilling well. The purpose of t
How to classify core barrels? A section of pipe connected to the upper part of the drill bit to accommodate and protect the core during core barrel.

Product Description
RC hammer 4” RE004
Product description:
Reverse circulation hammers are specifically designed for all kinds of exploration drilling, like deep hole and in-pit grade control applications. when you are exploring potential sites or working an existing mine, RC hammer will guarantee high performance, exceptional reliability and dependable support.
RC hammers and bits are used in hole drilling in mines, hydrology and water well, geothermal well, geothermal air conditioning well, geologic exploration, gravel stratum, etc. Especial suitable for complicated formation (Formation loose, difficult to drilling and unstable of hole wall), exhausting for deep hole, environment protection.RC hammers and bits are used in hole drilling in mines, hydrology and water well, geothermal well, geothermal air conditioning well, geologic exploration, gravel stratum, etc
When breaking a Hammer down, avoid placing breakout tools in the mid-section of the cylinder (barrel). Recommended breakout points are 130mm from each end of the cylinder. Wrap around chain type breakouts are recommended (see diagram). When holding bits for breakout, use a secure plate or pot to grab the bit head, but never on the gauge row buttons.Especial suitable for complicated formation (Formation loose, difficult to drilling and unstable of hole wall), exhausting for deep hole, environment protection.
