    4.0 out of 5 stars Pain to setup initially but extremely useful once you do

    I ended up using this on White Oak wood and Hard Maple wood to allow for a flawless corner in my kitchen. Overall the corners turned out amazing but it took a ton of work to align on my routing table. I wish the router bit had a bearing or something similar as most tongue and groove bits do. If it did have this then you could just center your fence to this bearing and that would be it for alignment. However this set does not have that so you end up using a ton of scrap wood to get the settings dialed in. When you do though the lock is amazingly durable and impossible to tell that the two boards are joined. I am extremely happy with the finished product just frustrated with the initial setup. One thing I did that I would highly suggest is to keep some pieces of wood after routing them and dialing in the settings so that in the future you can just set the table to match these patterns again. This means that you really wouldn't have to go through this hassle every time after setting it up initially. Overall I am very happy with the outcome and I would buy this bit set again.

    5.0 out of 5 stars Double check the quality control before spending an hour trying to troubleshoot a defective bit.

    This was my first time using a miter lock bit, so of course I didn't know what to look for as far as quality control so hopefully this review will help someone not waste so much time. The whole premise of this bit is that the tongue and groove fit together to lock the 2 pieces of wood together. Therefore, the tongue and groove should be the same width in order for the 2 pieces to fit snuggly. If you look at the bit I received, the tongue is significantly larger than the groove and therefore no matter how hard I tried I could not make the 2 pieces of wood fit together. I didn't realize that this was an issue until about an hour of trying to troubleshoot it. Save yourself some time and just look at the bit before you use it. Because otherwise you will waste your time trying to make a defective bit work. Quality control was pretty poor on this one. The other 2 bits were fine, but I needed that specific size otherwise the miter doesn't work!

    3.0 out of 5 stars First time using lock mitre bits

    Okay, so watched a lot of video's on how to set these up, and yes, it took me a while, and went through a lot of sample wood to make sure everything was lined up correctly. Once I got it all lined up correctly, I used it on my plywood furniture project. I had some HUGE tear outs. By huge I am talking in some cases 2 to 3 inches of a layer or 2 of the plywood. Using 3/4" plywood. I am an amatuer woodworker, not a professional, but the tearouts should not have happened. Thankfully, The tearouts wont be seen in the finished project, but Might be worthwhile to spend a bit more, and get a quality set of bits. On the bright side, the joint is much stronger than a standard mitre joint.

    Great bits once you got them setup. No instructions included and I had to go to You tube and search and watch multiple videos to get the set up right. Shouldn’t be this hard.

    Finally used it and the angle is off so the corner is open by about 2⁰. It was worth a shot at this price point but unfortunately didn't pay off....
