With its multiple interlocking fingers, this bit creates maximum gluing surface area for superior edge joints and splice joints. The fingers have a wedged shape, which when clamped together, helps to close up the joint without any gaps. 3/4" guide bearing.

The bit works well. It was used predominately in 5/4 red and white oak (end grain). I did use a backer board and had no chipout. Cuts were crisp and clean.

Woodworking Experience:
Works great but i wish it worked on 1.5 inch pieces so i could do the ends of 2x4's. I have a bunch of 2x4 reclaimed deck redwood that i want to turn into trim and molding. Now i have to rip it first. The photos are just test pieces. I will run the redwood through the planner to get rid of the weathered wood.

Good functionally, would have been nice to get some at least minimal instructions on how to use it to flush join two boards.

First Time User
First time user of this type router bit, but I had lots of smaller pieces of lumber that I wanted to use for a butcher block project.
Some wasted material in the learning process but things worked out in the end and I'm happy with the new toy

This product works as described. I am new to finger jointing, so using this bit was a learning experience for me. There are a few videos online about how to use this bit and that is should be used in a router table. For the application that I needed, using a router table was not possible. Using some scrap wood, I fashioned a very simple jig which allowed me to use the bit without a router table. See the attached pics. The guide on the jig is a cut-off from one of the cherry boards. The reason this board is used as a guide, is because it is the same thickness as the wood that I am finger jointing. When using the jig and bit on boards that are 3/4 of an inch thick, it's easy just to cut one end of one of the boards you are joining and then cut the end of the 2nd board by flipping it over. Do this after the initial setting of the bit. This should produce boards that join fairly even without having to re-position the bit. When using boards of a bigger or smaller size than 3/4", it's best to use a test piece for each jointed end reserve as templates and adjust the bit for the partner end between joining ends. This bit seems to be kind of fragile. A tooth broke off my bit. I know not why? I planed the boards myself and there was no metal, however, Rockler was more than happy to replace it because they have excellent customer service!

Least expensive I could find. It gets the job done. I'm more or less happy with it. I think I just need to find the right glue that doesn't gum up the joint.

I bought finger joint bit and thought there would be instructions on how to use this bit. But I did not receive any can you explain this bit's use?
Moses C on Feb 21, 2017
BEST ANSWER: 1. Center the bit on your stock.
2. Set your router table fence even with the bearing.
3. Rout the first board face up.
4. Rout the second board face down.
5. Continue alternating faces until all boards are complete.
can the finger joint bit also be use to join small pieces edge to edge?

What is the amount of offset of the height setting to match boards end for end?
Doug98105 on Jun 6, 2016
BEST ANSWER: It will be 1/2 the thickness of one full section of the bit: i.e. From the bottom of one of the blades to the exact spot one up. If the measurement is 5/8ths of an inch then the offset will be 5/16ths. A lot of guys have problems getting this just right and find it easier to make the sides oversized and assemble the four sides to then cut the top and bottom to size.
Is this a carbide bit? I don't see that it says anywhere on the web page.
A shopper on May 15, 2015
BEST ANSWER: The package the bit comes in describes using K20 tungsten carbide in the manufacture of the bit. So the answer is Yes
Ordered and received the bit. The cutting edges are covered in black elastomeric (rubber") material and the remainder of the bit is covered in plastic. Do I peel all this off or just run a piece of scrap through the bit?
Stephen O on Aug 15, 2018
BEST ANSWER: I just removed the black plastic,haven’t used it alot yet,need to practice a bit more before making the real thing
What is the maximum thickness of material you can use this router bit with?
Robert B on Jun 9, 2019
BEST ANSWER: I was able to rout finger joints in 1 3/8" thick oak. It took a few passes using scrap pieces and adjusting but afterwards was able to make the finger joints so that only a minimum of planing was necessary.
