Help Identifying Router Bit

I have never seen on like that. That doesn’t mean you can’t buy one on every corner but I have never seen one like it. Are you sure someone didn’t make that tool. It looks like and end mill that has had some work done on it. I imagine it is aggressive too.

I am with Grandpa on this one. I would send an E Mail to Whiteside with a photo and if anyone can help they should have an answer. My best bet is an end mill that someone converted.

Thats an end mill with a bearing slipped onto the shaft.

Try a google image search for a “shell end mill”.

Looks like and end mill with a bearing as stated above. Wholesale Tools has a big selection of end mills in the inexpensive category.

I’ve seen his before.
It is a spiral upcut end mill template bit.
From my understanding, it is made for using a template pattern to cut patterns to a certain depth. The spiral pattern quickly brings the material up, out of the cut, to help prevent burning.
The article I read about them hinted that they were popular in home made router based CNC machines.

I am looking diligently for the supplier, since I seen it before. If I find it, I will report back.

Hello,

The Wood Whisperer used that kind of bit in one of his videos.

http://thewoodwhisperer.com/trestle-table-pt-2/ about the 35 mins mark he talks about the bit.

I found a site that sells it:

Take care,

I am so glad you found that. I can quit looking now.
I’ve been searching like crazy for it. After seeing the video you linked, it made me more curious.

That looks like an end mill. I’ve only seen them used in machine shops. They usually do the same thing as a planer.

Yea, after doing some research I think its based off a END MILL design, but used for wood. Found out its called the Big Daddy Pattern Bit and is sold by William NG Woodworks. Probably marketing it as a bit for thicker hardwoods in a router table, I’ve seen some shelix heads being used on a shaper, maybe grizzly brand?

Anyways the guy that posted the picture on his blog got back to me and told me what it was, I believe he was using it to template maloof chair legs, which are pretty thick stuff. If I remember correctly, Maloof said when he used templates he used a shaper to mill his parts off the templates… guess this bit is trying to have the same capability but on a router..

I was interested in it because of the blade design. I have to template some walnut endgrain on my router table and thought that the shearing cutting action of the bit might leave a smoother surface with less tear out, kinda like a shelix cutter head. Plus, it goes into the omg this thing is cool category I have to have it, but I think Im going to stick with my normal template bit for now considering the need verse cost of this bit.
