Recently purchased the larger version of the bit to build some box newelposts out of three-quarter inch quartersawn white oak. Setting the bit up to the right height and getting the fence the right distance took quite some time, and I burnt through a lot of practice stock to get it dialed in but once dialed in the miters fit together perfectly. I would suggest to have your boards as perfectly flat as possible (as with any routing work) and if you don’t own a jointer probably best to pay to have somebody surface your boards. Make sure that when you are planing all your material to your desired thickness that you also do so to quite a bit of test material. Even on my second run using a different thickness I probably had to make about 12 test cuts so plan ahead. I used this on a router table mounted as a tablesaw extension.

The Instructions included or not very helpful, check out the instructions for the similar rockler bit online as that is what I ultimately used to help dial it in.

Expensive, but a great way to hold tight mitered corners.

The Lock Miter Bit works well. It does take a little time to get it set properly. There were no directions on set up, this would be helpful. I do like the joint it makes.

What is the minimum material thickness that can be used?
Dave T on Mar 18, 2017
BEST ANSWER: After some trial and error, I have used this bit successfully on 3/4" oak and am both very happy and amazed at the results. I believe the minimum thickness with the bit I have is 1/2 stock. There is a smaller bit which accommodates 3/8 to 1/2 inch stock as well.
is this a carbide cutting edge?
steve d on Aug 14, 2018
BEST ANSWER: Does not look like it is. Packaging does not mention carbide edge. If carbide, Freud hid it very well. Cuts nicely as is though.
Is there two bits for the lock miter? If so are they sold separate
Doug T on Jan 24, 2017
BEST ANSWER: No, there is only one bit which comprise the lock miter. The joint does involve two separate cuts, which requires a bit height adjustment (depending on what you are trying to achieve) and each of the two pieces of wood that comprise the joint are passed through the bit differently. One run through on its "edge" and the other while laying "flat."
Like any other new endeavor, practice on scrap wood first similar in thickness to the intended project. Also, although not necessary if you are patient, there are lock miter templates available to speed up the "set up" process if desired. To effect the cut on each separate piece of wood, several passes are necessary as this bit is large, and requires a specified working rpm.

The joint is very nice once you begin to get use to making the height adjustments. Good luck in your endeavor.
Is there a bit that can be cut across a 1x4 long ways to make a sort of picture frame style joint with a lock built in?
BillD on Oct 26, 2017
BEST ANSWER: Lock miter bits work well for making picture frames. There are videos available on the interned that show them being used. It is best to practice on scrap wood first.
Does Freud have a set up block for the lock miter bit ?
Bob P on Apr 20, 2015
BEST ANSWER: I don't think so. But it isnt that hard to setup You'll have to do some test cuts both horizontal and vertical to get it setup.
