    Alo'ha, looks like a diamond drill but cutting diamonds should be in front and water dizas (muddy liquid) (small pipes) behind-to cool the drill and take out particles on sidewalls of the main pipe that is not yet seen through the drill goes downwards /upwards.Drill can rotate-like this one or be in softer ground so called bumper drill...
