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.

Great jig
This is one of the best jigs I own. It makes the installaton of the Blum slides faster, easier and also more precise. It is a much better jig than the blum one.

Worth its weight in gold
This saves a lot of time and headache during the final assembly and completion of the Blum slides. It literally takes be about 2-3 minutes to set up the bit, set the jig on the drawer box and drill the hole in the exact location at the EXACT angle necessary. Again, big time saver.

Rockler JIG IT® Undermount Drilling Guide
I completed two drawers before I received this jig. Had to re-drill or expand the rear guide holes on both drawers because of slippage of twist drill and angle of holes for front mounts. The next two drawers were dead on for both and went in without any rework on both of them. Great aid and real time saver no matter how accurate you can measure.

I’ve used a different jig for the Blum drawer guides, this jig work just as good and it was less expensive. I would recommend this to anyone buying Blum tandem drawer guides.

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.
