The GraBit works with any reversible drill to remove screws with stripped heads, regardless of size or drive configuration (Phillips, star, square, hex, and more). It works on bolts with snapped-off heads, too.

The two-sided bits lock into the damaged screw head in two simple steps: Use the stubby drill-bit end to hollow out the screw head. Then use the threaded end of the bit, with the drill running in reverse, to extract the screw.

In our test, however, it didn’t extract drywall screws. Those screws are hardened, so the GraBit couldn’t cut into them.

A set of three bits handles screw sizes from No. 6 to No. 14. The set sells for $25 at www.shoppraziusa.com.

A wheel-type gauge is the easiest to use, and this wonderful Veritas model is a steal at $38.
