AWESOME!! (5/5), Nov 3, 2015

By Michael Barsky (Philadelphia PA US)

Picked this up today, because I needed to assemble a banister I made out of 4 raised panels, that were 6 1/2x28. I was skeptical about it working on a long surface, but man was I surprised. I got back to the job set the bit up in table and ran two pieces. Perfect the first time, incredibly easy to set up. I ran two of the pieces through on edge in three passes, both sides. Ran the other two through face up in three passes. They slid right together and were perfectly square. These are a must have for me now!!! Love it!!

Review of lock miter bit (4/5), Oct 28, 2015

By ralph (Harrisburg Pe US)

I have just finished using the one that I had purchased and have had terrific results. It is so much easier and effective for making the 90 degree corners on all pieces of wood. It takes some time to work with, but once you become familiar with it, the router bit produces fantastic results. All of the corners are square and very strong.

limit the glue (5/5), May 22, 2015

By tom siegel (Charlevoix MI US)

Test cut in 12" long dry oak was absolutely perfect. Found the set up guide blocks useful.

Lept to a 7 foot long cut in walnut for box beams for a king size bed. Absolutely loved an earlier review suggesting leaving 1/16th or so in thickness when milling your own stock. I used a drum sander to remove the excess after the miter .. avoided risk of snipe on the planer .. got a knife edge.

Had early problem with glue-up. The tongue and groove, when using a single bit and single fence setting, are apparently so tight, there is little to no room for glue squeeze out .. especially in a 7 foot long joint.

Resorted to gluing only the 45 degree flat surfaces, leaving the tongue and grooves dry. Much better fit. Got the minimum desired squeeze out at the 90 degree inside and outside edges making for a very tight looking edge.

In my project, with the box frame still in three sides, I glued in some ribs to make up for any loss of strength I caused by not gluing the tongues and grooves.

strong drawer joint (5/5), May 31, 2013

By Ken Rupkalvis (San Antonio TX US)

I used this bit to make many drawer boxes for a very large desk. It's rock solid after glue up and very square off the router. I found the setup block helpful in that it cut setup time significantly.

Nice Joint (5/5), Oct 24, 2012

By John McCormick (Spring Te US)

I too used this bit to make table legs because I did not want to show a glue joint down the piece. I was very happy with the outcome. The setup block was nice but not 100% necessary.

Also, if you are milling your own wood to thickness, I recommend that you leave a sixteenth or so on the thickness before routing the lock miter. This way, you are not producing a sharp edge to ride on the out feed fence. Mill to final thickness after the miter has been routed.

Best of all, the joint produces a near perfect 90 degree joint with little effort. Just make sure to clamp it tight.

Very Versitile (5/5), Sep 5, 2012

By Paul Smith (Altoona PA US)

If you want to build a table leg made from 4 pieces of wood this is the answer. Used it to make legs for a Craftsman design dining room table. Many of my woodworking pals thought the legs were solid, but I explained how this bit works and a couple added this bit to their collections. Also, this is a great bit for making drawer boxes. The front, sides and back interlock and make a joint of unprecedented strength. Also, the set-up block is a near necessity for accurate joints. There are alternative set-ups but the block is easiest.

I have used this product and found it to be very useful, and would recommend it to anyone wanting a secure joint in their woodworking. The video is most helpful.
