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.

Constant Hammer Shank - Model 543-4M
Constant Hammer shanks or 'Rattler Bits' are used in a hammer in place of a standard drill bit and allow the piston to continuously cycle when the air is turned on.
They are typically used when a hammer and drill string is too bogged to rattle the drill string.
