Lets you quickly and precisely drill all holes required to install Blum Tandem undermount drawer slides onto your drawer boxes.

Rockler JIG IT® Undermount Drilling Guide

Item #
94% of 100

In order to install your Blum Tandem drawer slides, each drawer box must be drilled with six precisely-aligned holes. Our Undermount Drilling Guide makes that process fast and easy. Simply lay the guide on its side and butt it up to the front corners to drill the smaller angled holes that accept the locking devices. Not only will the location be spot-on, but the 15° angle is also set. Your bit won't wander, and driving the screws is a cinch. To drill the 6mm holes in the rear of the drawer box, stand the Drilling Guide up on its legs and position it over the notch. The end result is a drawer box that clicks into place on the slides perfectly, every time.

Worked flawlessly and was fast.
I had 18 drawers to install in the kitchen and and this little jig made that incredibly quick and simple. The best part is that it is small enough to fit nicely in my apron pocket and costs less with the bits and stops included than the Bluhm version without the bits. Using two drills for the different sized bits speeds up work vs swapping bits for every drawer.

It did it's job well.
The jig worked well. The instructions were easy to understand, and making necessary holes using the jig was much easier than it otherwise would have been.

Excellent Value
I am an English major, and I teach middle school. I am not a skilled woodworker by any stretch of the imagination. I like doing it, though, and I like learning how to do it. This jig is invaluable. Very simple to use. I had tried mounting drawer slides without it and... I needed this. Very quick, easy, and straightforward - and it works. Thanks!!!

What is the jig's hole spacing for the locking device? Blum changed it from 25mm to 32mm, is this for the newer 32mm device?
MarkB on Feb 3, 2016
BEST ANSWER: It is for 32mm devices
Where can I order a wrench and extra screws?
Mike M on Mar 15, 2016
Will this work with the Blum depth adjustable locking device for inset applications?
Nick V on Jan 2, 2018
BEST ANSWER: I used the jig for Blum drawer runners for face frame 21" drawer slides. 5/8" side, rear tilt adjustable. The part number was 563H5330B. I don't know if these were depth adjustable devices.
will this work with other brand under mount drawer slides such as grass dynapro ?
Dan R on Feb 19, 2019
BEST ANSWER: I have no idea, Rockler should be able to answer that for you. If the description doesn't specifically mention that brand, I would not bet on it.
Does this jig work for the 563 (5/8" drawer side thickness) & 569 (3/4" drawer side thickness) drawer slides?
Dennis on Apr 3, 2017
BEST ANSWER: This jig will work for both wall thicknesses. The tool is seated against the inside wall of the drawer bottom. so the rear locking pin on the drawer slide is always in the same location regardless of box thickness.
