Freud Lock Miter Router Bit - Ideal for Professional Woodworking, CNC/Table Routing, Interlocking Joints - 2-3/4" Diameter, 1/2" Shank, 12,000 Max RPM - 99-034

I purchased this particular corner lock bit because of the previous reviews and the Freud reputation. It is also big enough that it covers all of the wood thicknesses I'd be using for projects with just the one bit. The bit is well-balanced and cuts very smoothly. The nature of this profile is that set up takes a bit of doing to get the two cuts to align perfectly. I made a new sacrificial guide fence so that I could embed the bit into the fence face. I am well pleased with this purchase and highly recommend this lock miter bit by Freud.

This thing worked perfectly...once I figured out how to dial it in exactly. Do lots of test pieces and make incremental adjustments until it's perfectly dialed in.

This is a very nice bit. After struggling with less expensive ones this is a joy to use. I find setup to be much easier - don't know why but the acceptable range of stock thickness for this one is greater than others I have used. I suspect that is why setup is easier?

I have lots of Freud bits, and have always been happy with them. Bought this one because I wanted a better solution for making lots of miter box joints. Normally I just cut a 45d angle, lay them out with painters tape, glue them up and close up the joints - this looked like a great way to make this a more structured joint that didn't depend on painters tape for alignment.This is a VERY BIG bit. Lots of mass. Even with my router table properly configured, I struggled to get boards through it. With the board laying flat on the router table I was able to get it through ok, but when you have to set the opposite board up against the back fence - well, let's just say it feels super unsafe. A lot of that bit has to be exposed and even with decent fence alignment, feather boards and a ton of adjustments, it never felt safe to use.The lower score on this review isn't a reflection on the build quality of the bit - it's very good. It's just a reflection on how dangerous this bit is in practice.

My husband bout this for a project he is working on. Actually, this his the second one. The first one arrived loose, bouncing around inside its case. So he sent it back for a replacement. A tool like this you do not want to take a chance on seeing how big it is and how fast it turns! This is a big router bit, heavy, well made. It is also very sharp. The instructions are mostly useless if you have never used this bit before. The setup block that you can get with it gets you close but the rest is trail and error until you get it dialed in. Once there, does what it was made to do well.

Works as described, heavy duty bit.

Takes some trial and error to get properly set up, but not all that difficult. Once dialed in, makes a wonderful non-slip joint for gluing. Aligns joint to form perfect 90 degree angled surfaces. Great product!

It works great
