Rockler Finger Joint Router Bit - 1-3/8" Dia x 1-1/2" H x 1/2" Shank

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.

does a great job works great on router table

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.

Had to lengthen several hard maple pieces to make a shuffle board. Worked well for me.

fits the bill.

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!
