45 Degree Lock Miter Router Bit 1/4 Shank for 1/2", 3/4", 5/8" Cutting Height, Woodworking Tools Joint Router Bits Easy to Create Lock Miter Joint 3PCS

Easy to use and makes a great lock miter. Used mine to make false beams for a great room.

As described

I watched a couple of videos on how to set it up. Tried it myself and it's not as easy as the videos showed. You can't just slap it together. You're going to need a few test pieces to get it right. And you need to get it perfect or you'll have gaps.Otherwise, these bits made their cut into hardwood plywood with ease without overheating and never lost their sharpness from use. And, once properly set up, the end result looks fantastic.

Haven’t used them much but I did once and it was great

I found it very hard to setup. I have some reclaimed wood that I was hoping it would work with, it doesn't.

First use and I'm very pleased withe the results. Plenty of videos out there on seeing up these style bits I just wish these came with some instructions

These bits are not within proper tolerances and they have a steep drop-off after the 45 miter edge unlike higher end bits. I used a good bit of stock to eventually figure out that the 1/2" bit in this set I needed will only work properly if I plane down my stock to 7/16ths. This proves that the bits are off and inaccurate up to 1/16th of an inch making them unusable because they will leave that large of a gap in the joint and I need to use these on 1/2” stock. DO NOT WASTE YOUR TIME WITH THESE BITS! I thought I would save some money since I only needed them for 1 project. Lesson learned I guess. There is no substitute for quality router bits.

I like that these are great for our purpose, but wish we could have gotten them more quickly for when we needed them.
