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.
