The Kreg Concealed Hinge Jig, Model KHI-HINGE, is a cabinet hinge drilling jig built to make concealed hinge installation easier and more repeatable. This is a concealed hinge jig designed for drilling accurate 35 mm cup holes for concealed cabinet door hinges. If you are building new cabinet doors, replacing old hardware, or hanging a full kitchen of doors, this jig gives you drill-press-style accuracy with an ordinary hand drill.

What matters here is not just that it drills a hole, but that it helps drill that hole in the right place, at the right offset, and to the right depth. The built-in indexing tabs help position the jig on the door, the measuring scales help repeat the same setup across multiple parts, and the adjustable cams let you match the hinge offset required by the hinge you are using. That saves time when you are doing batches and cuts down on ruined doors when layout is off by just a little.

Kreg includes the parts that do the real work: a drill guide, a 35 mm carbide-tipped drill bit, and a stop collar with hex wrench. The drill guide keeps the bit tracking where it should, while the stop collar helps control drilling depth so the hinge cup is not too shallow or too deep. On cabinet doors, that kind of consistency is the difference between hinges that sit properly and doors that need to be reworked.

The body is made from glass-filled nylon, which is a smart choice for a jig like this. It keeps the tool light enough to move around the bench easily, but durable enough for repeated use. The jig is also straightforward to set up, which is a big deal for beginners who want clean results without buying a dedicated shop machine. At the same time, it is robust enough for pros knocking out repeat cabinet door work.

In practical use, this jig is aimed squarely at concealed cabinet hinges, often called Euro hinges. Those hinges work well and stay out of sight, but they demand a large cup hole in a very specific location. The Kreg Concealed Hinge Jig removes a lot of that guesswork. It is especially useful when you need repeatable hinge boring for face-frame or frameless cabinet projects where door fit and reveal matter.

There is also a jobsite-friendly side to it. Because it works with a hand drill, you can use it in a shop, garage, or on-site install without dragging in larger equipment. If you are adjusting cabinet doors during a remodel or replacing damaged doors in place, that portability is a real advantage. Just note that while the jig includes the 35 mm bit for the cup hole, Kreg states that a 1/16 inch drill bit is required for hinge-mounting screw holes and is not included.

Compatibility is simple and useful: this jig is built for concealed cabinet door hinges and uses a standard drill-based workflow instead of a dedicated boring machine. For woodworkers, cabinet installers, remodelers, and serious DIY users, that makes it an economical way to get cleaner, more predictable hinge placement. If you only hang one door every few years, it keeps the process manageable. If you are doing a kitchen full of doors, it helps keep your results consistent from the first panel to the last.
