"Precision Tools for Professional Results"

Big Gator Tools was established in 2005 and is now marketing the most universal patented drill and tap guides ever sold. Guides are made from a special nickel alloyed steel that is heat-treated and ground along bottom surface to assure stability and accurate perpendicular alignment on flat surfaces. All guides have a 90 degree V-groove along the bottom that allows perpendicular alignment on round parts as well as corners.
