Is a cordless drill attachment patented?

Short answer: specific designs of a cordless drill attachment have been patented many times, but "a cordless drill attachment" as a general idea is not what is protected. What matters is the exact combination of features in your version.

What this means for your idea

Because patents cover specific combinations of features, the useful question is not “has a cordless drill attachment been patented?” but “has my combination of features been described before?” Tools and office products differ in grips, adjustment mechanisms, and how blades or bits are held and changed.
