An intraosseous injection device includes a tool having a distal portion, a proximal portion, and a solution dispensing opening. The distal portion has one or more cutting surfaces. The tool can be coupled with a protective carrier. The tool can be rotatably coupled to a tool actuation mechanism. A housing has a distal end and a proximal end. The housing releasably receives a solution cartridge containing a solution. A solution dispensing mechanism dispenses solution from the solution cartridge. A gripping member grips a proximal portion of the tool. A rotation device rotates the gripping member and thereby rotates the tool about an axis. The proximal portion of the tool connects directly to the solution cartridge such that solution from the cartridge can be delivered through the solution dispensing opening. The tool is configured to rotate relative to the solution cartridge.
