During operation little soil is brought upwards by the auger that lateral stresses are maintained in the soil and voiding or excessive loosening of the soil minimize.

However, if the rotation of the auger and the advance of the auger are not matched, resulting in removal of soil during drilling-possibly leading to collapse of the side of the hole.

When used with a pile frame, back guides are bolted to the hammer to engage with leaders, and only short leg-guides are used to prevent the hammer from moving relatively to the top of the pile.

Double-acting hammers are used mainly for sheet pile driving.

Vibratory hammers are usually electrically powered or hydraulically powered and consists of contra-rotating eccentric masses within a housing attaching to the pile head.
