Review on Big Gator Tools STD1000DGNP V-Drill Guide: Accurate and Versatile Drilling Solution by Phil Anderson

Not sure what metal this is made of, but it's a solid piece of hardware, much stronger than I expected. While I haven't tried it, I think it would be pretty difficult to drill this thing if you didn't have the right equipment (not that you want it, but the point is that your drill bits won't damage it). The numbers on it aren't always easy to read, but it's good for drilling straight holes. There is a V-groove on the bottom so it can fit round objects, cylindrical materials or outside corners. It has lines that match the pilot holes so you know exactly where to drill. While the lines are useful, I'd like them to be darker and deeper so they're easier to see. I personally just look at it. Overall, this tool works as advertised and does what it is supposed to do. I like it, I find it satisfying and I'm sure I'll use it many times. You can't break this thing or wear it out, and no doubt it will be with you long after I'm gone. Have fun drilling.
