Reverse Circulation Hammers & Bits
Black Diamond's 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 BDDRILL RC hammer will guarantee high performance, exceptional reliability and dependable support.
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. Wrapy 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.
This information is included with every Hammer purchase.
