Hmmm, this is kinda nice! If only the driver bit tip was in focus. Still, I guess that makes me focus more on the drill instead, which is ultimately the subject. I think a white background would've been more flattering to this subject. Also, the arm appears to be in an awkward position, as if the photographer himself was holding the drill. Is that a flashlight on the bottom, might have been neat to have it lit for this shot. Overall, it is a 7.
The colors here are lending more to a red than an orange. It's close enough to let it slide, but figured I'd mention it. You're use of DOF is well suited. Lastly, the off-shades below the drill bit are distracting.
