essential addition if you bought the beadlock kit
I had a bunch of frames to make for my wife's upholstery education business and decided to try the beadlock system over conventional mortice and tenons. So much easier but at 6 joints per frame the bought tenons become expensive quickly. the router bit paid for itself in spades. the frames were 11/2"x 2" so using 2x3 poplar, I was able to use the milled 1/2" offcut to make the tenons. The other advantage over the bought tenons is you can adjust the fit to be tighter or slightly looser by adjusting the thickness at the router table and make custom lengths. Hopefully Rockler will bring out a cutter for the 1/4" and 1/2" beadlock system in the future.

Like any other it you have to set up the height and fences. I recommend setting up the fence dead on with troughs in it vs the newbie instinct to set up the material to go between it and fence. Also, use featherboards.

Great products and service
The shipping took a little long, but the service of Rockler pals is flawless... Received my products in Mexico City and, of course, will repeat the experience.

Cheap as chips
Compared to what I would pay in the Uk this router bit is brillaint value and is high quality.

I couldn't wait to get it into the table, followed an online instruction video and after one foul up I was knocking out tenon stock like a man possessed, this will pay for itself in no time at all at the rate I'm converting scrap timber I'll be selling it at a profit! OK perhaps not......

Good buy
If you buy this keep in mind that milling the wood first is a very good idea. I milled the wood down first and using the bit was easy with the use of feather board. You can produce product fast.

works great after some practice
With zero instructions, no videos, no anything, this bit took a round 8 feet of 2 x 2 scrap boards before I got it working for me. Now that I have it dialed in, it's saving me tons of money and shop space as I use scrap wood for my loose tenon joinery

Works well once you get the hang of it...
This bit works as expected after running through a ton of stock to figure out how it needed to be set up. Evidently, you're supposed to trim your stock to 3/8" thick and align your router table fence with the trough of the "beads" in the bit. It would have been most helpful to have instruction sheet in the package! Maybe then I wouldn't have run through a ton of different widths of hard maple and walnut to get it to cut properly

Down the road this will be more cost affective while allowing me the option of choosing the strength of my tennon materials.

I have the beadlock pro kit and the tenon router cutter extends it use, enabling me to cut my own tenons rather than hunting on the net to purchase ready cut stock.

I bought the Beadlock 3/8" kit from Rutlands in the UK and was shocked when I discovered the price of the tenon stock so decided to make my own. I could not find anyone in the UK with the correct router bit so bought this one from Rockler.

Will the 1/4" and 1/2" versions of the Beadlock router bits be made available?
Jim_Day on Dec 11, 2016
BEST ANSWER: Sorry no, only the pre-made tenon stock is available for the 1/4" and 1/2" sizes.
What are the instructions for making tenons with this bit?
CHARLES B on May 6, 2017
BEST ANSWER: Mill your stock to 3/8" and the proper height (~1-3/4") of the cutter, then run it through the cutter on both sides. You might need to do a few tests to make sure that you have the right stock thickness to end up with the correct bead thickness. You want to use a featherboard to keep the wood tight to the cutter, and best to mill a number of pieces all at once. Overall, it's a very easy process.
What guide do I use to drill the holes for tenons this bit makes or do I just use a drill press without a guide?
Louis W on Apr 5, 2017
BEST ANSWER: I used the Beadlock Pro as the guide. The Pro has a clamp that enables you to accurately position the guide.
I believe it would be quite difficult to manually drill the 3/8 holes for the tenon it produces as they overlap!
Initially I found it really difficult to use the carbide bit until I saw a technique that I found on Utube.
Good luck.
Is it possible to cut stock without a router table?
Matt H on Aug 13, 2015
BEST ANSWER: no, and you really need to use a featherboard on the table as well to ensure even thickness.
does this bit work for the 1/4 and 1/2 tenons as well?
Jeremy A on Jun 27, 2015
BEST ANSWER: To the best of my knowledge each bit is unique where the radius of the flutes match the radius of the drill being used - as such you will need other router bits matched to 1/4" and 1/2" tenon sizes
