  • make sure it fits
these work great. make sure your drill has a lip to put brace on. they work better on a drill press.

  • It helped me to solve a problem
The adapter came quicker than I thought, which is good. It came with no instructions, But it wasn’t difficult to assemble just being intuitive. Clamping it to the drill guide was a little tricky. But keep in mind this is designed to be a solution to many problems. Therefore, it may not be a fix for every application. After about 45 minutes I succeeded with the installation. So, to answer the all encompassing question, would I recommend it? Well, a cautious “yes.” You have to “fiddle” with it, but it did, in my case, work just fine. ... show more

  • Works, but be careful!
It's very flimsy and might not fit all drills. When making the holes, there's not much structure mounting and it wobbles a bit on our plug in DeWalt drill.

  • Be patient
The metal the screws is made of is soft and immediately rounded out so be careful but the product works. Might take some messing with to get it just right.
