Rated 4.7 out of 5 by 10 reviewers.
Rated 5 out of 5 by life saver very sharp. used it to drill out a broken bolt in a seven inch deep hole. October 14, 2014
Rated 5 out of 5 by 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. October 7, 2014
Rated 5 out of 5 by 1/8 IN. X 12 IN. THUNDERBOLT AIRCRAFT LENGTH BLACK OXIDE DRILL BIT Very sharp. It does the job I needed it to do well. September 30, 2014
Rated 4 out of 5 by 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.
