Abstract
A debris ejector for a drilling tool is disclosed. In some cases, the ejector may be provided, for example, as part of a tool assembly (e.g., where ejector is coupled with bit, or both a bit and cup). In an example, a tool includes a cup and a drill bit passing through an internal void of the cup. The cutting end of the bit extends out the open end of the cup, while an attachment end of the bit extends out the back of the cup. The tool further includes an ejector within the cup. The ejector spins with the bit and independently of the cup. In one example, the ejector includes ramped or angled wings that eject material within the cup. In another example, the ejector includes tapered wings with straight and/or angled walls that push material out of the cup through one or more holes of the cup.
