The V-Drill Guide is like a portable drill press for precision alignment. V-groove along the bottom of the guide allows for perpendicular alignment with all drill sizes on round parts and corners. Bottom surface is precision ground to assure stability and accurate perpendicular alignment on flat surfaces.
Drill guide is sized for drill bit sizes: 1/8" to 3/8", and made for 17 standard drill sizes (1/8 to 3/8 in 1/64 increments).
Guides are made from special nickel alloyed steel that is heat treated for durability. Drill Straight - Every Time!
Drill Guide comes with a handy plastic storage case and is 100% American Made Quality.

Dill guide was fine but, I ordered three 12long X1/8 drills and they came mark/tag that but when I measured the dia they measured 3/64 dia not what I ordered or expected. You need to check your stock and see they are marked wrong. Let know when you have corrected your stock as I need to order the 1/8 dia 12 drills ASAP
