Key Features
True 32 mm spacing Drills shelf pin holes on 1-1/4 inch (32 mm) centers, so adjustable shelves sit level and your rows stay consistent from top to bottom. Hardened-steel guides Hardened-steel drill guides keep the bit from walking, which is how you get clean holes without the wobble that makes shelves rock. Ready-to-drill kit Includes the 1/4 inch brad-point bit and shelf pins, plus on-board storage to keep the small parts from disappearing between jobs.
Overview
The Kreg KMA3225 Shelf Pin Jig 1/4 in is a shelf pin drilling jig for woodworking and cabinetmaking that helps you drill straight, evenly spaced shelf pin holes fast. This is a shelf pin jig designed for drilling adjustable shelf holes in cabinets and furniture. Model Number: KMA3225.
The big win is repeatable spacing: the drill guides are laid out on 1-1/4 inch (32 mm) centers, which is the standard used in the 32 mm cabinet system. That means your hole rows line up cleanly from one panel to the next, and you can add shelves to existing bookcases or build new cabinet sides without laying out every hole by hand.
Accuracy comes from the hardened-steel drill guides. They keep the bit centered and supported so the hole stays round and clean. Pair that with the included 1/4 inch (6 mm) brad-point bit, and you get holes that start where you want them and finish without blowing out the surface as easily as a standard twist bit.
For real shop and jobsite workflow, the jig is made to move quickly: you can drill six holes per setup, then reposition to keep going. If you are doing tall pantry sides or long bookcase panels, you can snap two jigs together to extend the run and keep the same spacing without remeasuring.
Kreg also built in features that help beyond shelves. The jig is 32 mm system compatible for layout tasks like locating hardware positions in frameless cabinets, including concealed hinge plate screw locations and the front hole location for drawer slide installation, using the molded alignment marks and indicator window.
If you want adjustable shelves that look like they came out of a cabinet shop, this jig kit is the straightforward way to get there, whether you are a pro installer cleaning up site-built shelving or a DIYer upgrading closets and built-ins.
