Newdeli 3PCS 45 Degree Lock Miter Router Bit Set 1/2 Inch Shank for 1/2”, 3/4", 1" Cutting Height Joint Router Bits for Creating Lock Miter Joint

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.

I used these to create some faux beams. Worked very nicely after watching a few videos and taking time when adjusting!

Have used this set a couple times now... and the bits are sharp and cut well. I watched some you-tube videos to learn how to set them up correctly (no instructions). Once I got them set up correctly, I made a template-block I can use to set them up quicker the next time.If you do the cuts in 2-3 passes- instead of 1, it really minimizes tearout. I've only used them on white oak so far, but that's a pretty good test.The only downside is the lack of instructions.

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.

Heavier than expected. A really nice addition to my toolbox.

Once I figured out how to set up the bit, then it worked pretty well. However, it seems to have a lot of tear-out. I hope that’s the correct word. There is tare along the edges of the cut. So, impossible to use with plywood, even Baltic birch. I did use it with poplar and the tear out was less, but still there. 3 stars for the design, lowered for the sharpness of the blade. Also, the cut is a little complex, which increases the chance of errors in the cut. Not saying don’t buy. Just saying you may be a little disappointed.

Works beautifully but I think it would be a good idea if they included in the sale of this bit the setup gauge. Charge a few dollars more and the gauge made it simple to set up.

WhoRa!!!
