Overview
Use our Louver Router Bits to create your own shutter louvers in 2-1/2" or 3-1/2" widths. The louvers interface seamless with other elements of the Rockler Shutter System. The included ball-bearing guide runs along the middle of the shutter slat—just rout one side, then turn the slat around to rout the other side. 1/2" shanks ensure a smooth chatter-free cut.
To learn how you can build your custom shutters with ease, view all of our Rockler Shutter Jig Templates and select the style that is perfect for your application.

What is the recommended speed for this bit?
What size louver will the 2 1/2 inch cutter cut? Or is it a cutter to shape a 2 1/2 inch louver?
BEST ANSWER: I used this bit on louvers that are 3" wide and it worked fine. It seems the wider the louver the flatter the finished profile is in the middle. I don't know if you have used this bit yet, and I am sure you already are careful with your router. I used this on maple on a router table and a couple of the louvers chipped out enough that I had to remake them. Also, given the length of the bit it can pop the wood out if you try to take too much off at once. It is hard to use a featherboard to hold the piece once the rounded profile is cut on the opposite from where you are working.

What is the cutter made of?
BEST ANSWER: At the bottom left of the website there is an info box which says the bit is made from K10 and K20 carbide. The box is generic, but it likely applies to this bit as well.

what is the recommended thickness (center) of the stock for the 2 1/2"-width louvers?
BEST ANSWER: All louvers should be 3/8 no matter width. The radius opposite the bearing determines thickness. i ran these on a table router and ran more than 600 louvers or 2400 passes. it will require some finish sanding and i recommend setting up some feather boards to avoid snipe. I ended up putting a spacer on the out-feed fence to keep the part vertical on the last 2 passes. This bit works well.

do you sell the wood used for the shutter louver router bit?
BEST ANSWER: Well not really they don't. Not in basswood at least but u don't have to use basswood. They do sell the shutter louvers already routed in basswood ... this is what I do. If u want to do the routing urself then u will have to buy 3/8" stock (1/4" actual dimension) or 1/2" stock (3/8" actual dimension) depending upon the width of the louvers u are making.

Is it necessary to make any adjustment to the router position when flipping the louver over to do the opposite side?
BEST ANSWER: No. Once you establish the correct height for the bit, you leave it there for the duration. I was really impressed with how well the system worked and how beautiful the shutters turned out. I made mine out of solid cherry and they look great. My wife's favorite wood project ever.

Excellent
First time I ever used a router table and used this bit to make 30 10" louvers from 4 foot poplar boards. Shipping was quick. Note my louvers came out a quarter inch shorter in width than the original 2'5" stock but I'm not sure if that is normal or my set up was off, like I said it was my first time using a router table. Be nice if they included a diagram showing how to set the bit for us rookies.
