Newdeli 45 Degree Lock Miter Router Bit 3-Piece Set, for 1/2”, 5/8”, 3/4” Cutting Height, 1/4 Inch Shank. Easy to Create Lock Miter Joint

They worked. The blades are high quality. But there were no instructions for set up. I spent a while watching YouTube videos and cutting up scrap to practice with and got poor results on my project anyway. But here’s what I learned. 1) don’t even try to use these without first fine tuning your table and fence. Your set up needs to be perfect. 2) don’t even try to use these without substantial and copious feather boards. An auto-feeder would be ideal for longer boards but you’ll get away without it. 3. If you’re making a box or a hollow column and you have tried for hours to position the fence and blade perfectly for a perfect 45-degree bevel but it isn’t coming out exactly right, give up. It’s actually easier to have a slightly longer toungue on two sides and a slightly shorter tongue on the other two sides as long as you account for this by ripping to the correct width before doing your edges on the router table. You still end up with a perfect box and it’s actually easier to clamp up. Great product but if it’s your first time using this tool, you’ll want to do your homework first.

Takes a little bit of knowledge and time to set this bit up correctly but when set up right it works very well and makes a nice joint. Recommend watching some videos on how to set up a Lock miter bit was very helpful for me.

Makes nice cuts. No instructions on how to use it but after a few attempts, I figured it out.

Amazon had the very best price for these compared to anywhere else. The miter turned out perfect, and the drawers have went together quite well.

Buen material, uso lijero

Seemed to dull after a dozen uses. Probably good for the occasional use

I initially removed a star for the lack of a dimension but decided to add it back since you can work backwards from other provided dimensions to get the fence located. The fence needs offset 0.25" from center (toward the workpiece), and the height of the bit is obviously 0.75". Works well. Very tight joint.

Good router bit I would recommend
