Review on Premium Drilling Centering Alignment Shelf by Jeff Jackson

I work as a contractor and I like a product that makes my job easier. This device definitely does. Can be set up quickly and very precisely. Easily stackable, allowing you to drill a series of holes longer than the template. It is also very nice that you can drill the front and rear holes at the same time, which saves the conversion. The only complaint I have is that the drill bits provided aren't the best - they leave the holes a bit ragged. I use some Wood River bits that I think I got from Woodcraft instead of the ones that came with the jig and they leave cleaner holes.
