1/8 in. x 12 in. Thunderbolt Aircraft Length Black Oxide Drill Bit is rated 4.8 out of 5 by 15.
Rated 3 out of 5 by from 1/8 Black Oxide -->>12"<<-- Aircraft Length Bit It's a fine drill bit. However, the height listed in the Specifications came out of thin air. This bit is 12 inches long, not 7.75 inches.

Rated 4 out of 5 by from Did the job; wasn't heavy duty though It served my purpose but was expensive for what it was. Of course, I'm not a pro and I'll probably be lucky if I ever find another use for it. But I needed the task to get done. So value suffers but as far as Overall rating and Quality, I'd say it's good.

Rated 5 out of 5 by from Great for deep guide holes for wood screws! I bought this for my son's cub scout den. We built candy dispensers and this worked great for the adults. I have to say that the length made it difficult for the 10 year olds to keep square but that is to be expected.
