Kreg KMA3225 Shelf-Pin Jig 1/4" (6 mm) - Shelf Pin Drilling Jig - Create Perfect Holes for Wobble-Free Shelves - Drill Guide for Straight Holes

Used recently to prepare 48" wide x 84" high shelving unit with adjustable shelves on each side. The Kreg KMA3225 Shelf-Pin Jig worked very well to align holes for shelf pins for drilling. Very good tool, easy to use and quality made.

Just used this. I’m a total novice. This worked great. I will say that there is some tear out from the drill bit. It leaves some wood around the holes. I stained & polycrilic’d before I drilled the holes (totally forgot). If I would’ve drilled the holes first then sanded again, all would’ve been fine. Its size works well and I never missed a hole or hole location.

My contractor agreed to build a shelving system from scratch for my linen closet but I wanted adjustable shelves, so I purchased the Kreg KMA3225 Jig so his assistant could drill the holes. The system is reasonably priced, comes with quality hardware and bits and includes easy to follow directions and even a video on the company website. I'm very happy with how everything turned out. The holes bore cleanly, accept the pins easily and look very professional. Since I'll never use the jig, and being a minimalist, when the job was done I gave it to the assistant as a thank you gift.

I'm not really a fan of adjustable shelves. They seem cheap to me, a kind of Ikea throwback. But when they are specified on a cabinet build, you install them. Manually getting all the holes precisely accurate so you don't get a wobbly shelf can be very hard. With this jig its actually kinda easy. The trick is the first hole markings. They have to be accurate to a tee. Then you clamp the guide, drill the open holes and if you need more holes move the jig up or down and use the last hole drilled to locate the jig by putting your drill bit through the hole in the jig into the last cabinet hole, clamp the jig again and now you have a whole new set of perfectly aligned holes to drill. The steel guide inserts in the jig helps you have a true 90 degree angle on the holes too. I've used others without the steel guide inserts and they wear out and allow angled holes very quickly. If you are just going to use the jig once, then there are several cheaper alternatives, but if you expect to use it for more cabinets go with the Kreg brand and it will last you a long time. One tip: Always use the drill stop on your bit. Tape alone is not good enough. The stop will prevent you from ever having the bit catch harder wood and blowing through the side of your cabinet. Happy building! :-)

Generally, this works just fine. But when you use the jig for the first set of holes, then move it down by putting the guide pin into the last hole you drilled, watch out for the considerable play in the guide pin. It is less than 1/4" diameter so it introduces positioning slop in the jig to start the next set of holes. This can lead to the 2nd set of holes on one side of the cabinet wall being slightly off from the 2nd set on the other side.make sure you insert the guide pin, then pull down on the jig to use up the slop before you begin drilling the next sets of holes.

This Kreg Shelf-Pin Jig is exactly what I needed for building adjustable shelves. The design is simple but effective—drilling straight, evenly spaced 1/4" holes is now quick and foolproof. The guide lines up nicely, and the included drill bit is sharp and precise.What I really appreciate is how secure and wobble-free the shelves feel once installed. No more guesswork or uneven pins. The material is sturdy, and the jig stays in place well while working.If you're into DIY cabinetry, bookshelves, or closet projects, this jig is a must-have. Makes a pro-level difference with minimal effort!

This works great for predrilling holes in cabinetry. It's easy to make sure they are even on both sides of the cabinets for level shelves. This took makes it easy to install the shelves.

This is a nice pin hole jig . I really like the drill bit sleeves that prevent accidental crooked holes. Also being able to attach multiple together is a nice feature.
