Milescraft Cabinet Shelf Hole Jig

I used this jig to drill consistent shelf-pin holes throughout the cabinets I built for my shop. The metal guide bushings keep the drill bit aligned and give you evenly spaced holes without having to measure and mark every single one.
 
I originally tried a cheaper plastic jig, but the holes started wearing out and my shelf pins weren’t fitting correctly. I switched to this Milescraft jig because of the metal guides, and it was a much better setup. If you’re building cabinets with adjustable shelves, this is one tool I’d spend a little more on.
