Any DIYer will find years of usefulness for an array of gear and home projects, repairs and maintenance out of Big Gator Hand Drill & Tap Guides. They can be used on flat surfaces (like skis & snowboards), corners and round items (like ski poles and bike frames). With or without clamping, these handy guides should be in every DIYers toolbox.
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.
