The Kreg KMA3232 Shelf Pin Jig - 5 mm is a shelf pin drilling jig kit for cabinet and furniture work where shelf holes need to be straight, evenly spaced, and repeatable. This is a shelf pin drilling jig designed for drilling adjustable shelf pin holes on a 32 mm cabinet system layout. Model Number: KMA3232.

The whole point of this jig is spacing and alignment. The drill guides are centered on standard 32 mm increments, so you can add adjustable shelves that match existing cabinetry or build new boxes that follow the same system. That saves you from laying out every hole with a tape and square and hoping your rows match side-to-side.

Accuracy comes from the hardened-steel drill guides. On cabinet sides, a hand drill will try to walk, especially on veneered panels. The guides keep the bit tracking straight so the holes stay round and consistent, which matters when you want shelves that do not rock or sit crooked.

Setup is straightforward: use the fence to register the jig to the workpiece edge, then drill the hole pattern. You can drill six holes in one setup for common shelf ranges, and when you need more, you can connect a second jig to keep the same spacing without restarting your layout.

Kreg also built in alignment features that make it useful beyond shelf pins. The jig includes molded-in alignment marks and an indicator window for locating mounting screws for concealed cabinet hinge plates and for helping locate the front hole for drawer slide installation in frameless cabinets that follow the 32 mm system.

If you build or modify cabinets, closets, built-ins, or furniture, this is the kind of jig you keep in the truck because it turns a time-consuming measuring job into a repeatable process you can trust.
