Auger Pick And Drum Cutter Pick :- With three drum options (for soft, medium and hard rock), and a selection of pick choices (suitable for all strata, from soft rock through to abrasive rock) guarantees high performance levels in the toughest of environments in both loosening material and reducing overall wear. Componentry has been specifically selected to provide maximum penetration and minimum vibration and noise levels. A heavy-duty sealing system means working underwater to a depth of 25m is also possible.
