Infinity Cutting Tools 1/2" Shank, Lock Miter Sr. Router Bit, 5/8" to 1-3/16" Stock | Carbide Tip | Heavy-Duty | for Handheld Or Table Mounted Wood Router

Although I haven't had a chance to test it with a bit in my router yet, I have done a few dry runs matching the product with a bit. It looks like it should work, especially if I follow the tutorial video.

Over priced

If you’ve ever tried to align your miter lock router bit and waste a lot of scrap wood while being totally frustrated, then infinity cutting tools miter lock gauge is ingenious. It takes some finagling but works with other brand router bits. I’ll come back and give my update when I take this jig through its paces.

this toool is expensive and not really needed unless you are a newbie like me

Did not seem to work with the bits I have. Apparently one is supposed to purchase the bit from Infinity that the product was demonstrated with for another $90 to $100. I alresdy have 3 different size bits and I was not able to work it correctly with either of the two smaller bits -- wasted an entire 1x4 trying.

worked and easy to use

It can help get the correct joint but sometimes it doesn't get accurate enough

This probably should get 5 stars as far as product design and quality manufacturing, it is real time saver for aligning the bit to the wood to be routed. But $9.90 for an item that is feather light and the size of a postage stamp is a rip off. Not only that, they added a store catalog to the envelope so I ended up paying the shipping cost for the catalog.
