ABSTRACT:
An underwater machining apparatus that is capable of drilling completely through a surface and collecting all machining debris is described. The underwater machining apparatus, in one embodiment, includes a drill body, a drill motor coupled to the drill body, a drill bit coupled to the drill motor, and a drill bit sleeve positioned coaxially around the drill bit. The underwater machining apparatus also includes a vacuum assembly coupled to and in fluid communication to the drill bit sleeve. The drill bit sleeve is configured so as to permit water to be drawn through the sleeve by the vacuum assembly, thereby removing the machining debris. The vacuum assembly includes a collection container configured to collect solid particles of machining debris while permitting water to flow through the container.
