The fit and finish of Xdovet's new angle drill jig is outstanding. It has 30, 45 and 90 degree angle guides. Being made of aluminum alloy, they have manufactured this tool to exacting tolerances. It also looks great painted orange with the white lettering and they are very easy to see. Each size guide is clearly marked to be sure the correct size guide hole is being used. This new tool looks great on my shelf, but it's preciseness is what really matters.This is an angle guide with four different drill sizes and is able to drill at three different angles. I bought this angle guide because I needed to be able to drill some exact 90 degree and 45 degree dowel holes. I wasn't disappointed in anything about it. My angles matched up perfectly and my joints fit together to the exacting standards I needed. In fact, once I sanded the pieces I joined, the angles were so perfect that it was difficult to see where the pieces all went together.When I inserted the drill bit into the guide hole, I was surprised by how tight and perfect the fit was and that there was no side to side movement or wobble at all. It was as tight as it could be made, giving me the exact diameter holes I required. The four drill bits are sharp and drilled through the wood I was using with no issues at all. I don't have any cable railing to do, but my joints and angles are pretty much the same and this angle guide will work for railings just as it did for my project.If you want precision at a really great price, this is the one to get. I highly recommend it to anybody.
