11/32 router bit

[Max]

Does anybody make a router bit for dadoes to fit 3/8" (nominal) plywood? I've checked: Whiteside Eagle America Infinity CMT Freud MLCS Woodline Rockler Grizzly Woodworker's Supply Price cutter

No luck

Max...

If you have (or are willing to buy) a 3/8" collet, you can order an

11/32" solid carbide end mill from Part numbers are:

1-428-SEM343-2 11/32 with 2 flutes

1-428-SEM343-3 11/32 with 3 flutes 1-428-SEM343-4 11/32 with 4 flutes

They're all listed at US$23.24

Those OK to run at router speeds (25Krpm) ? I was under the impression that milling machines ran at considerably slower speeds, and would hesitate to use a mill in a router.

They generally work at least as well as router bits, are more consistantly sharp, and frequently cost less. Nearly all of the end mills in my catalogs are labeled "center cutting", which means you can plunge straight down.

Of course you can have any profile you want so long as it's straight. :-)

I thought the same thing a couple of the guys on a CNC ng told me about some of the larger faster mills that cut metals at feeds and speeds make 25kRPM sound pretty slow. There're some pretty scary machines out there!

Yeah, but your typical router doesn't include a cooling fluid deluge system and a wrap-around safety enclosure like these big CNC machines do.

I also found one at

Nor does it need them. 25K is well within the safe rpms for these tool bits. Just be careful ... they tend to be razor sharp when new.

I didn't see any 3/8 inchers there.

If you can't find/don't want to buy here are a couple of solutions...

1. Make a square router plate with the edges at varying distances to center; for example, -1/32, -1/16, -1/8. Use a 1/4" bit and the widest side of the plate for pass #1 then turn router so appropriately narrower side is used to guide for additional passes.

1. Make a 1/4" dado and rabbet the ply as necessary. My favorite as the shoulder on the ply tells you when it is fully in the dado.

3.) A parallel sided dado jig, known around here as "Leon's Jig", used with a 1/4" bit. The jig adjusts to the thickness of each piece of plywood. It's even self-squaring. Line up the jig to what will be the top of each shelf, and let the bottom of the dado fall where the ply thickness tells it to.

Here's one version:

You are correct. End mills are basically the only bits I've used in a plunge router for the past few years. It is the only type bit, AFAIK, sold for use with the Multi-Router, which uses a router of your choice to drive the boat.

You turned me on to these guys:

And, for the OP, I've also had good luck with spiral upcut, two or four flute, "end mills" of extra lengths, available for deep mortises, they are often cheaper. Last time I ordered, the 1/4", 5/16", and 3/8" 4 flute end mills were $16, $19, and $27 respectively.

Useful to know.

Just like the Model T Ford, eh?

Thanks, Morris -- I'll look into that next time I need something of the sort.

I didn't see any bits for 3/8 ply there. but thanks for the URL

That's the process I've been using but I figured *someone* must make a bit for 3/8" ply. Morris tipped me off to an end mill and I think it will work.

Hi,

Amazon has a two sets of plywood sized bits from Freud, # 89-650 & 90-106.

Same set at Woodworker supply:

But, But, I can't find the 11/32 bit by itself and I just bought a set of 3 bits for 1/4", 1/2", and 3/4" ply from Infinity. :-(

Thanks,

Max

about 10 minutes, max... :)

Did you try Amana Tools and/or CMT?

Might fire a note off to John Wirth and Woodworkers Supply -- he's always looking for "stuff" to add. Printed catalog only shows down to

1/2" nominal for his undersized ply set, but mine is old and didn't look online...

The Freud has been ordered. $15.11. But with "shipping", it's $25.07 Would someone tell me how an item like a 11/32 router bit could cost $9.96 to "ship"? But, thanks, it does solve my problem. And I will send a note to Wirth.
