There are various forms of drilling equipment that can be used to drill holes into a number of different types of surfaces. For example air core drilling uses steel or tungsten blades in order drill holes into surfaces while cable tool rigs are commonly used to drill water wells, something that can be useful when looking to water or irrigate farmland. You can find listings of a number of forms of drilling equipment on the Totallyplant.com website, allowing you to find something best suited to your needs while at the same time helping you to save money by buying used rather than new equipment.
