I have been intrigued by these large diameter spiral flush trimming bits for a while now. I’ve used plenty of spiral bits, both upcut and downcut variety, but wanted to add some large diameter spirals to my arsenal. This is the Whiteside UDC9112 which is compression style spiral bit for clean top and bottom edges. You can get this in a top bearing, bottom bearing or combo bearing like this one. I chose the combo bearing for a wider variety of applications.

So how does it work? It trims whispers from hardwood like a delicate shave with a sharp razor. Honestly, the shavings that come off your workpiece look very different. Fine whispy curls of hardwood like they came off a finely tuned hand plane. Cut quality is fantastic. No tearout. No fear of grain direction. Clean cuts top and bottom.

I think the compression spiral technology, along with the large 7/8” diameter work together here to make such a nice cut. I most always run a handheld router counterlockwise around a board to avoid a climb cut. However, this bit handles a climb cut without any drama. I experimented with router RPM, and this large diameter bit ran best at speed 4 out of 6 (which would be somewhere around 15,000-16,000 RPM). Another thing I noted is the bit was quieter than my straight bits. You’d probably want to use a 2+h.p. router for handheld work. Any router table with a 1/2” collet will accept this bit.

Is it as big as it looks?
Here’s the Ultimate Flush Trim bit next to a 1/4” upcut spiral bit for comparison.

...and all for the low low price of $175.00

Very good review Willie. Much appreciated.

Great review pinto’... thanks for the effort to post.

Must admit I have one and love it… in fact I have the “other two”, to maximise depth (missus had 3 jobs at the time)...

PS. Those large bearings are great to help me identify them from the 1/4” bits.

Hey Jerry,
I know, not cheap. But if you’re working with Peruvian Walnut at $15 per b.f. it starts to make sense!

Okay, okay…. After 11 years here and 71 furniture projects posted, I start making lures a few months ago and that’s how people know me? A lure maker? I’m the guy who recommended the Yonica router bits awhile back because they’re actually pretty good and half the price. On the other hand I am very cheap…. er frugal.

I have to admit thought that router bit does look pretty badass.

Now that’s what I call ”Hook, line and sinker”... two on the one cast… and a single bait.

pottzy, I knew you were in construction… but I didn’t think it was digging deeper holes!
