JIG IT Undermount Drilling Guide - Durable ABS Plastic Drill Angle Guide w/Steel Inserts - Drill Guide Jig for Blum Tandem & Drawer Slide – Ideal Woodworking Tools Includes Drill Bits, Collars & More

This review is specific to the Blum Tandem Plus Blumotion slides and locks. this is a must have jig. I was considering not getting it , but wow, this makes the installation a breeze. I am sure you could try to mark and drill all the holes and drilling for the front locks is probably not too difficult but marking and drilling the back holes for the two tabs need to be close to perfect. This jig does that. It puts all of the holes exactly where they need to be.

This saves you a ton of time and is very easy to use. the alignment is always correct and totally worth the money.

Works great to help with installing Blum under mount slides. Follow directions or watch a video and it only takes a few minutes to learn.

I bought this jig when I started building a new set of cabinets and wanted to try using Blum under-mount drawer slides. It is a good design, is well made and includes good instructions. Under mount slides require you to drill 6 holes in the bottom of each drawer, some at an angle, and this jig makes alignment easy. The kit includes the correct metric drill bits and stop collars. That said, it is not too difficult to install the slides without a jig. Glad I bought it, but it may not be worth the cost if only installing a few slides and you are on a budget.

This jig is easy to use and made the drawer slide installation go quickly and painlessly. It is cheaper than the Blum brand one, but I don't see a difference in their functionality. The holes I drilled using this aligned perfectly. Would definitely buy again if I needed another one.

Great jig for making drawers with undermount slides

I love this lil guide. It makes drilling the mounting holes for drawer hardware a breeze to install. The angle was always tricky to get correct before this purchase

Works as advertised!
