Good day! Thank you for your question about this Milwaukee 4136. This diamond coring rig is not used for drilling a well. It is used for drilling holes through concrete, tile, and masonry or stone. The maximum depth it can go will be about 36 inches and it will be the same thing in stone. For more details, please check the specification sheet provided above. If this is what you're looking for, just click "Add to Cart", fill out the required fields, and you're ready to go. Have a wonderful day ahead!
