Review on Professional Maple Tapping Drill 64 by Tony Morton

This drill bit may be marketed for "Industrial and Scientific" use, but don`t be fooled. Despite its name, it's made with subpar materials that can't withstand heavy use. On the plus side it's relatively cheap .But you'll end up paying more in the long run when it inevitably breaks or malfunctions. Stick with a more reputable brand for YOUR industrial and scientific drilling needs..
