How deep can the “Explorer” drill system go, and can it go through rock?
The “Explorer” is designed to be used for shallow well drilling (up to 100 feet). As packaged, the EXP-50 will go down 50 feet. The system can go much deeper, but this distance was based on field reports and drilling logs from missionaries around the world. We determined that in most of those wells water was hit at far less than 50 feet, which allowed us to concentrate on the portability issue (how to meet the 50 pound per bag airline restrictions). We offer extension rods if you need to go deeper, or you can build your own extensions in-country with local materials. Most portable drilling rigs cannot go through solid rock, and the EXP-50 is no exception. However, we do include a cracking bit that gives the “Explorer” some advantages over other systems with regards to drilling through difficult soils. The cracking bit can be used to break up compacted gravels, small rocks, and sandstone, making it more likely that you can keep drilling when you encounter these obstacles. In addition, t
