The Diamond Pier Impact Bit is used to drive Diamond Pier Pins in. Can be used with a standard automatic breaker/demolition hammer that accepts a 1-1/8" hex shaft. Typically higher impact electric hammers, or standard air jackhammer are used, particularly for dense soils. Roto-hammers will not be adequate.
