Pengo introduces the Bolt-on Rock Head (BoRH), which transforms the general purpose Aggressor into a rock-ready auger. The BoRH’s innovative wear caps provide a smooth transition and protection when fastened to the general purpose head. The BoRH locks into place using the wear caps and existing pilot bit. The wear caps’ lugs interface with the existing recesses in the Aggressor head, which allow for unobstructed removal of spoils from the hole. The BoRH features the new P21-RR carbide tooth. This tooth has an enlarged shoulder that increases holder protection during drilling.
