The Duradiamond system with or without dust extraction and uses diamond drilling machines. The system with dust extraction can be used for light industrial use, not only keeping the dry drilling process dust free but the core bits last longer. This system also operates from the inside wall to the outside and can be used in high rise situations. The “without dust” extraction system will also produce a clean hole but is not as occupant friendly or as efficient as the “with dust” extraction system and is therefore better suited for drilling from the outside wall, into the property.
