Review on Neitra 30 45 90 Angled Drill Guide Jig with 4 Bits for Cable Railing: Efficiently Drilling Angled and Straight Holes in Wood Posts by Emmanuel Nguyen

This guide allows for 4 different sizes but I prefer using the smaller sizes except for 1/4 for my size brackets. This drilling guide worked great for my 30 degree angle holes and my 45 degree angle holes of 1/4”. Even worked with the 90 degree 1/4” hole.The first thing I did was test that each hole would work with the included drill bits and I was quite pleased that they were no issues with the machined guide holes. This guide is built solid with line markers both on top and bottom that lineup. This gives me the confidence that when I am drilling I will have the wire rail in the same place on each 2 x 4 or 4 x 4 post.
