What is a cabinet hinge jig?

If you haven’t made cabinet doors with concealed hinges you might not know this jig exists.

However, concealed hinges require a jig to ensure three things happen:

  1. First the hinge cup is drilled to a precise depth
  2. Second the cup must be placed an exact distance from the door edge for proper hinge operation
  3. Lastly, the hinge must be located at the right location to clear cabinet frames and shelves.

And all of these tasks benefit greatly from a concealed hinge jig as it will put the hinge cup hole in EXACTLY the right location and with a drill stop, allow you to set a precise and repeatable depth to the hole.

Who Makes THem: Manufacturers

In woodworking if you say “jig” then a blue brand named Kreg jumps to almost all woodworkers minds. So, of course, they offer a hinge jig.

But surprisingly, there just aren’t any other major manufacturers other than knock-off brands you’ll find at online retailers. Which, for a few dollars more, there’s no reason other than to go with the Kreg KHI-HINGE jig  for brand reputation.

Drilling concealed hinge with a drill press

Since depth and placement are critical there is one alternative to a cabinet hinge jig: a drill press with proper setup and an edge guide.

To use a drill press for setting up and drilling concealed hinge cup holes you’ll need to follow the same steps as for a hinge jig:

  1. Locate your hinge location
  2. Use an edge guide to control distance of hinge cup from door edge
  3. And lastly use the drill press depth control to set the proper depth

In fact, for larger door runs, this setup can be easier than a jig. But, for smaller jobs, the hinge jig is faster, portable and less bulky to store.

  1. Always use a test scrap of wood the same thickness.
  2. Setup the test piece, and jig by making sure the jig is the proper distance from the edge.
  3. Then, drill two hinge holes the proper depth (go shallow, work your way to just the right depth).

  5. Lastly, install your test strip and make sure the hinges clear and everything things.
