A whole range of small drilling machines exist which can be towed by a car or built on the back of a pick-up, generally in the price range of US$ 5,000 – US$ 10,000. Most of these machines are limited to [[ Jetting - general |rotary jetting]] and [[Percussion - general|percussion]] (in the same way as the [[Percussion - Stone hammer|percussion gouge]]). The bigger machines and down-the-hole hammer systems are generally a lot more expensive (US$ 10,000).
