It makes a strong secure miter with no fasteners. Works great on plywood. But do a search for locking miter bit set-up. There are lots of Youtube videos and articles that will help make it a lot easier. ### ⭐⭐⭐⭐ Pain to setup initially but extremely useful once you do *by A***S on September 29, 2022* 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. ## Frequently Bought Together - MNA 45 Degree Lock Miter Router Bit 3-Piece Set, for 1/2”, 3/4”, 1” Cutting Height, 1/2 Inch Shank.
