I once bought a double bearing flush trim bit that was bigger that I expected. It scares me every time I run it, and it's only about half the size of that bit. I have to be careful to look at a ruler or tape measure when I buy bits online.
That bit looks like an absolute monster.

I wouldn't be concerned about breakage, with a cutting length/diameter ratio of less than 3. That is a tall cutter though, on a small shank, with a potential for removing a lot of material and for kickback. I would be cautious with a bit of that size in a handheld router. Cut close to the line so you are trimming a minimal amount. If you are often working with stock that thick you might want to use a shaper, if not a shorter bit would do. For comparison, I have a 3" diameter by 3" tall flush trim insert cutter running on a 1 1/4" shaper spindle.

Can you provide a manufactures link to the bit?

The YouTube channel "Make Something" also had a vid on this bit and I believe it scared him too

This format is indeed scary looking but there's a reason it's so massive...the length is required so that you can effectively use it for both top bearing and bottom bearing template routing on thicker material. An example might be a guitar body or a thick cutting board. I'm seriously considering getting one, even though I do a lot of my cutting on the CNC. There are just a bunch of tasks where having a stout and massive flush trim solution for the router table will be handy.

There's a tool for that: a shaper. I wouldn't trust such a bit in a router whether it was hand held or table mounted.

Why not worry about breakage? Lots of images on Google.Originally Posted by Kevin Jenness

snapped bits before non of them went anywhere just stayed in the wood or fell on the floor. Being in a shop when shaper guy throws knives thats not ideal.

whiteside ultimate flush trim is also 1/2 shank, but only 7/8 diameter and 1 1/8 CL, that seems more reasonable for a router
woodpeckers put out a competitor spiral double bearing that is 2" CL, but trimming 2" of material seemed too large for routing to me and I skipped ordering one

Fingers, if it were meThat is one scary looking bit!
